Accent MC (2006-11) :: Hissing Sound Coming From Rear Seat
So I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?

I have a 95 F150 4x4 reg cab long box with a 302 V8 and dual tanks... I was driving around yesterday when my truck started to lung and then the motor stalled... when I stopped moving I tried starting the truck and it started with no problem, so as i kept on my way, about 5 minutes later the same thing happened and it stalled again, (I have an automatic by the way). but this time before it stopped moving i pump the gas a few times and it fired back up and then stalled again... i switched from my front take to by back maybe thinking it could me my fuel pump in the tank but it did the same thing again about same time later... Would it be my fuel filter on the frame (like in line fuel filter) or why is it doing that? its EFI by the way.

1995 Chevy Lumina 3.1L Sedan with ~182K mi
Over the past 6 months, I have noticed fuel odor just about any time I turn off the vehicle, and I am also experiencing progressively higher levels of fuel tank pressure each time I remove the fuel cap. The fuel tank pressure seems to be greater the lower the level of fuel in the tank whenever I remove the cap. 6 months ago (~Sept) it was only a slight "hissing" periodically when removing the cap to fuel up, but now it occurs at every fill up and seems to have enough pressure to push the cap entirely off had I not been careful to slowly loosen the cap to relieve the pressure.
The entire fuel pump and sending unit assembly in addition to the tank and filter were all replaced about 4 years ago in May 2010 or about 28K mi ago. The issue has just come up progressively over the last 6 months.
Today, I inspected the evap. emission components and lines from the tank to the canister to the purge solenoid mounted on the rear of the engine. All lines are connected and seem to be in operable condition. The line from the canister to the purge valve mounted on the engine is completely free with no obstructions. I blew out the line with compressed air and absolutely no exiting particulates were observed. The lines on the bottom of the canister did not show any signs of wet fuel and there were no carbon particles present in the lines from what I could tell from disconnecting and inspecting. The vapor line from the tank to the carbon canister is not kinked or pinched in any manner.
I believe there is a fuel vapor check valve that resides inside the tank connected to the fuel pump assembly/sending unit. This was all replaced as a single unit as mentioned above. I am thinking this check valve may not be functioning properly and not allowing the vapor to escape into the carbon canister. I tried to apply slight pressure and vacuum on the vapor line connected to the check valve on the tank but no air was able to move in or out even with the gas cap off. However, I do have a full tank of gas right now, so I imagine the check valve will be closed.
The check engine light is not on but since this is an OBDI vehicle I am not sure there are any evap. emission codes anyway.
How can I test the gas tank vapor check valve? How can I test the vapor purge solenoid located on the rear of the engine? What malfunctioning component could be causing the excessive fuel tank pressure.
Ford - Aviator :: 2003 - Hissing Sound Near Rear Of Engine?
I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?

I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.

Caravan/Voyager :: Hissing Sound After Turning On Rear AC
I've got some trouble with my 2010 T&C Touring and the A/C system. I believe it is specific to the rear, but not 100% sure yet.
Here's the symptom, while driving home a few nights ago, I noticed a hissing sound from somewhere under the dash. Research led me to believe that the r-134a was low, so I bought a few cans and charged it up. I drove around yesterday with the fresh refill, and all was well. This morning, I noticed that I hadn't been running the rear A/C, and thus, not doing a full test.
So, I turned on the rear A/C and within just a few minutes, started hearing the hissing sound again. Flash back to a couple of weekends, I replaced brakes/rotors and while inspecting after taking a test drive noticed some water pooling up under the rear passenger side tire. I checked it out, but at the time, it didn't seem significant until today when I started to put this all together.
SO, my question is, what would be leaking right above the tire? Is this something that is super common and I could somehow convince my local dealer to repair out of "good will" like was happening with the '06 model year with a similar issue? I've had to do brakes, rotors and as a result of not knowing that Chrysler calipers can't be pressed in, but instead must be wound in, replaced calipers, and also an EGR valve all at the same time. So, needless to say, I'm not excited about doing further repair.
Touareg :: Hissing Sound Coming From Rear Windows When AC Is On?
Noticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....

This is on my sig truck. I can hear the pump running, and a sound like fuel spraying around inside the tank, but not getting any up front to the carb. What is the most likely culprit for this? Can't get the bed off, or get the strap bolts loose, so I haven't been able to "eyeball" anything, yet.

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!
View 8 RepliesChevrolet :: 1995 - Clunking From Rear End And Shake Can Be Felt Through Floor And Seat
I have a '95 Chevy 6.5 Turbo-Diesel Pickup. The past few days there has been a whining noise that went up and down with the speed of the vehicle. I decided to have it looked at this coming week when I have a day off but when I was driving home last night the whining stopped and was replaced with a clunking. It sounds like a pair of running shoes that have been thrown in a clothes dryer. When it clunks loudly there is a shake that can be felt through the floor and seat. I now have it parked until I can find out what is going on and if it is safe to drive to the mechanic or if I should have it towed.
View 3 RepliesFord Fuel System :: Rear Tank Leak - No Power
I have the dual tank setup & this is my problem.
Last year I replaced both tanks - the front was leaking bad and rear was starting to leak. After replacing both tanks, the rear tank (which I was using before) was unusable - it would idle fine and when applying throttle would stall out. The front tank's gauge did not work.
This week I pulled both tanks. Had new gauge assembly put on front pump unit. Also had the rear pump replaced with a new (rebuilt?) one. Installed both tonight. Now the front tank is running fine with a gas gauge. I Filled up the rear and once I had about 16 gallons in, fuel started leaking from the front top of the tank it looks like (where in-tank pump is). This leak has continued as the truck was turned off too. I think it may have stopped now, but its dark and I am parked on a hill. As another problem, I still have the same "stalling" problem. The rear will idle fine, but start to stall out when a load has been applied.
So to summarize:
- What is causing it to want to & stall out?
- Why am I leaking gas?
It seems to stop dripping gas after (maybe) the pressure is lower from leaking the gas out. Also, when 1st starting it up on the front tank, it wants to stall out...probably from the gas that leaked out while it was shut off? The truck will run for about 1/20th of a mile on the rear tank when initially starting it up before showing signs of stalling.

View 8 RepliesFord Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?
I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
Ford Fuel System :: 1984 - Gauge Does Not Work On Either Front Or Rear
I have a 1984 jayco mini 25 with a 7.5(460)in it. It has been in storage for the past 3 years and has not been started. It turns over and I do get spark. The problem is fuel. I am getting power when I jump the oil pressure switch and ground at the wires on the frame rail that go back to the tanks. My gauge does not work on either my front or rear so at first I thought it just may be as simple as a bad ground since the ground is used for fuel level as well as the pump but I wasnt that lucky.The tank switch is working, I can hear it. What are the odds of both fuel pumps being bad?

View 8 RepliesFord Fuel System :: 1987 F150 - Leaking Started From The Rear Tank
1987 f150 302 4spd 4x4. When I bought the truck 4 years and 12K miles ago the orig owner had just installed a new front pump (in tank) and new switch thing on the frame rail. He said shortly after that the rear pump stopped working so he just ran off of the front tank. That's what I've been doing also except as of the last few months it has started to leak from the rear tank (I don't ever put gas in it and was empty when I bought it) and dies periodically from time to time? Where the leak could be coming from. I do suspect the dying has to do with the leak though.
