Ford 7.3L Power Stroke (1999-2003) :: Installation Of Fuel Pressure Gauge?
I bought an Autometer 4763 gauge that didn't come with the correct fittings to plumb the sender into one of the extra ports on the back of the bowl. I went to the Ace hardware store right across the street and they didn't have anything (not surprised) and then Napa. They couldn't find a fitting to match either. He found that the plug threads are 7/16 20 tpi and the sender is 1/8" NPT. He suggested getting a 7/16 20tpi bolt, drilling it rifle-style, and then tapping it for a 1/8" NPT. The alternative, and what I ended up doing, was to use brass fittings to tee it off one of the supply lines to the heads. I ended up going that route but wanted to know if I should have looked harder for the right fitting.
Here's a pic of what I have now. I've test fit it, and it seems to work although I will need to insulate the hard lines because they rub due to the offset.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Fuel Pressure Gauge - Install Sensor Into Lift Pump?
I am installing a fuel pressure gauge into my 02 7.3 I went to the thread the sensor into the plug hole on the fuel filter housing and it wasn't threaded, turns out the sensor thread is slightly smaller and a different thread ... The directions say to install it into the filter housing or the lift pump ... So I'm assuming I have to go the lift pump direction of installing it but where the lift pump is or how to install the sensor into it while not throwing a code or causin problems ... A step by step and even pictures.

Two years ago I acquired a very very nice 2001 F350 DRW crew cab. The person I purchased it from put a Remanufactured 7.3 in it and set the truck up to pull wedge trailers. He put 25K miles on it and put it on Craig's list where I found it. It just turned over 300,000 miles.
One of the changes he made was to install a 70 gallon fuel tank in the frame rails below the bed. He told me that when the gauge reads EMPTY there is still 20 gallons in the tank. I remember him telling me that this anomaly is due to using the stock Ford pickup in the larger tank.
I have never filled the tank because so far the truck is used locally. I usually put 10 to 20 gallons in and when it gets to E I do the same fueling.
Then one day I turned the key on and the needle went up and beyond the full indication.
I can get under it and maybe the tank has some name or model number on it.
The truck runs fine, but the gauge concerns me. Eventually the truck will be making round trips from Chicago to our retirement home in Santa Fe, NM. It would be nice to have a working fuel gauge!
I have spoken to the person I purchased the truck from. He installed the tank as part of a complete upgrade that included a re-manufactured 7.3. The fuel tank is a 67 gallon Titan mounted between the frame rails. He believes that the original Ford sending unit was installed. That means it has 300,000 miles on it. I had the truck on a lift yesterday and it is a very tight fit. The garage said the best way to do the repair is to remove the bed. Six bolts, disconnect the tail lights and the 7 pin trailer connector and it is off.
So, my questions now are... Should I stay with a new Ford sending unit or are there better ones to install? Are there any other updates to the fuel delivery system that should or could be done at the time?
Ford 7.3L Power Stroke (1999-2003) :: Fuel Gauge Stuck On Full
Well besides the pyro breaking friday BEFORE live tuning,and the exhaust leak I gained on the way to Texas(not inpart of the pyro not working). Now the fuel gauge is stuck on full. It looks good,200+ miles and still on full. Could it be the gauge,or possibly just the sending unit? Maybe a fuse?

I've had an ongoing issue with my fuel gauge reading incorrectly, and now I'm trying to fix it! Basically, it will change all over the place while I'm driving (not erratically, but definitely moves occasionally). I recently fixed my overhead display, but the "miles to empty" display doesn't seem to be very consistent. It will read 450 miles to empty, and then the next time I look at it, it will have dropped 100 miles or something (after minimal driving).
So I'm wondering where I need to begin looking to fix this problem. I've replaced the dash cluster using Circuit Board Medics, so I'm fairly confident that's not the issue. I've read that it can be the fuel pump or the fuel tank sender, but how to check if these are actually the problem or how much time it will take. Luckily, I've never run out of fuel and been stranded, but I need to fix this or it's only a matter of time!
Ford 7.3L Power Stroke (1999-2003) :: Low Power - Fuel Pressure?
Low power on my 2003 7.3 F350. The truck runs fine but I can tell it is low on power (seat of the pants). I figured it to be fuel related so changed fuel filter and oil with no change. When that didn't work I installed a fuel guage and this what I found. Key on no start fuel pressure 45 psi. Start truck the pressure will get up to 61psi. Under a load it will drop down to the low 30s. I have dropped the tank mixing chamber screens clean and so was the tank. Changed fuel pump and now under a load it drops to the high 30s. Does this sound like the fuel pressure regulator is leaking by and causing low pressure under a load? Truck is stock besides superchips 1705 programer.

1/4 tank just kept cranking. Added some diesel and started right up thought it was bad fuel gauge. Went about a mile and shut down just off. coasted went got more diesel but this time cranked but no start. anti theft light was flashing too.
Towed home started right up after tow... Starting now... Tomorrow was going to change the fuel filter....
Ford 6.0L Power Stroke Diesel :: Fuel Pressure Gauge Install
I finally received all the parts needed for installing my fuel pressure gauge, but I am wondering if I am going to need a schrader valve on my fuel pressure line going to the sending unit, or if I am going to be safe with just doing a 6 time cycle of the fuel pump like we do when we change out the fuel filters. Seems like that should work for getting the air out of the fuel lines, same concept I would think.

Next mods are for the fuel rail cross over and the high pressure oil cross over. I see the unused ports will come in handy.
Fuel delivery? any specialty mods to run the fuel lines? I see it's a #4 ORB fitting. Anyone ever use a "T" or a splitter off the fuel bowl to have a quad line set up?
Saw the FRx from RiffRaff .... not sure how it eliminates air from the system 7.3L Diesel Fuel Rail Crossover? (FRx) 99-03 Powerstroke
Ford 6.0L Power Stroke Diesel :: Fuel Pressure Gauge Dropped Down To 50 Then Back To 65 At 70 MPH
Well, I was cruising down the highway @70MPH and notice the fuel pressure gauge dropped down to 50 then back to 65. Kept watching the gauge and it would swing back and forth from 55 to 65.
Got off the highway. Nailed it at the light and watched the gauge drop to 53 and swing back to 65. Fuel pressure is not steady either. It swings back and forth from 52 to 65. Thinking the pump is on its her last legs? Truck got 194K on her.
Ford 6.0L Power Stroke Diesel :: Leaking Fuel Line To Pressure Gauge
Couple of years ago I installed a fuel pressure gauge. I wrapped the fittings with teflon tape. Well within about a year it started leaking. So I shopped around and used Permatex Permashield fuel resistant sealant on the fittings. It says diesel resistant on the package. Couple months later leaking again. So I take it apart again, clean every fitting and follow the instructions to the letter. Well its leaking again. What will resist diesel fuel under 55 psi pressure. All the fittings seem to be pipe thread.

View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: Lost Fuel Pressure Going Down The Highway And Truck Died
Last night when i left work I noticed my fuel pressure was running about 77 psi, it normally runs about 68psi. today I took my daughter to practice and it was around 83psi, on the way home it was up to 95psi, so I parked it and took another truck to work.
About a week and a half ago I lost fuel pressure going down the highway and the truck died, finally decided my pick-up foot must have come off and had my sister in law bring me some diesel and it has drove fine ever since. (it was right at a quarter tank).
I have the FRX from riffraff and am thinking some pieces of that foot have got into the fuel bowl and plugging up the return. Things to check? Could it be a problem with the fuel gauge or wiring, and how to test them. It is an autometer gauge from riffraff.
It will probably be a few weeks before I can do much more than clean out the fuel bowl. I don't have anywhere inside to work on it and it's been rain/sleet/freezing rain/snow for the last 10 days. I have most of the stuff to do the hutch mod and its next on the list but was hoping to put it off till spring.
Ford 6.0L Power Stroke Diesel :: 2006 - Possible To Monitor Fuel Pressure With Gauge While Running?
OK so 2006 f550 6.0
If I want to monitor fuel pressure with a gauge in cab while running all the time... (not just testing) can I purchase one of the secondary fuel filter caps that have a port in the top and connect the sensor to this to run or is there a better way? (Or is that not going to work)
Cap I am talking about is something like this

(I know this is a combo kit but they do sell the fuel only) But since it has a threaded port in the top I could connect the fuel pressure sensor to that and go from there correct? Would that give accurate readings?
Ford 6.0L Power Stroke Diesel :: 2004 - Fuel Pressure Gauge Is Reading Dead 0
Just changed the fuel filter in my '04 6.0, no issues worked just like normal, filter primed truck started, great. Well now my fuel pressure gauge is reading dead 0, I know that can't be right because the truck is running, but noticed my fuel mileage seems about 2 mpg lower all of a sudden. Had R&R Injectors installed about 40k ago, figure it's just a bad gauge but wanted to check and see before messing with the frickin wiring. Also, have had a lot of pressure buildup in the coolant tank, has had head gaskets and studs, anything else it could be besides head gaskets? Have had a lot of wiring issues with this truck from the previous owner....
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Erratic Fuel Gauge - Level Would Register Full When Only Half A Tank Or So
I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

Ford 7.3L Power Stroke (1999-2003) :: F550 Runs Low On Fuel Pressure After Approximately 20 Miles Or WOT Throttle
Just joined today, I have a 2003 550 7.3. New HPOP, 3 new injectors, new seals on others, new fuel pressure regulator, new fuel pump, sending unit mod to eliminate filters. 733 HPOP pressure, 65 fuel pressure at idle. Truck runs out of fuel pressure after its warmed up and driven about 20 miles. Haven't checked voltage at pump while driving. I had taken it to a seasoned tech of 20 years and he had replaced HPOP and 2 injectors and it does start better but problem is still there.
