My '99 Passat V6 TDi has just developed a fuel leak somewhere around the tank outlet/inlet. I'm just going away on a trip (in another car) and can't get underneath to have a look-see just yet. Any typical problem in this area?
View 1 RepliesI had just replaced my the fuel pressure regulator in the fuel bowl because it appeared to be leaking from where the FPR is, now with the new FPR , it is no longer leaking from there but now leaking (fast steady leak while running) from the fuel rail outlet fitting... How do you replace these, why all of the sudden it started leaking there ???
View 9 RepliesI recently purchased a used 1999 F250 Super Duty with about 150k miles on it. The truck runs great and I have no complaints but there are a few things that need to be taken care of. It looks like there is a very small fuel leak where the filler neck ties into the rubber hose that runs into the fuel tank. There is a thin film of diesel along the side of the tank, on the leaf spring, the air bag and various other places. Nothing is dripping. I want to drop the tank and replace the hose. The Haynes manual says to depressurize the whole fuel system--is this really necessary if I don't plan on doing anything to the system aside from dropping the tank?
View 2 RepliesI was filling my DEF tank (2015 Super Duty 6.7) with 2.5 gal jug a few weeks ago and while I was filling it, the small black rubber air inlet on the container that allows air into the container while filling my truck got sucked into the container and then straight down into my DEF tank before I had a chance to stop the flow. Is there a screen in the DEF fill hose to catch foreign objects like is in the gas/diesel fill hoses?
View 6 RepliesI have a gas leak coming from the r/s rear of the tank. The exposed fuel lines all look good. It seems to be dripping down from the top but I can't see anything unless I drop the tank down. I ran the smoke tester but don't see anything comming out. Could I have overfilled the tank??
View 6 RepliesI 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.
The exhaust pipe connecting the cat and muffler is broken. However, the bolts connecting them are so rusted that look like one piece. Any tips on removing them off? I am afraid that PB blaster won't work in this case. I am thinking of drill them through, but afraid of damaging the cat.
BTW, my car's fuel tank has some leak. I can smell the gas. Is it safe to use a torch to remove freezing bolts?
I have a small fuel leak (97 Legacy Brighton wagon). The leak is detectable on the garage floor under the gas tank although I'm not certain that the gas tank itself is actually leaking.
View 3 RepliesI've had the Titan fuel tank installed for about a month now and am loving the extra range, although this morning I walked by the truck and got a slight whiff of diesel by the fuel filler door. I pulled out the flashlight to take a look, and noticed a really small, faint trail of diesel fuel running down the driver's side of the tank near the rear strap.
I crawled under the truck to inspect it as best as I could in the driveway, feeling around the sender, filler, and vent tube connections, and didn't notice any obvious puddles of diesel. About the most I got was some dampness around the sender unit seal, but it wasn't much, and could even be residue from the fuel lines dripping during installation of the tank. Based on where the trail down the side of the tank has formed, my best guess is it's going to be a filler or vent tube hose clamp that I didn't get tight enough.
Unfortunately I just filled the tank up last night and am headed out camping for the weekend this morning. I followed all the install instructions exactly, making sure to check the torque on the sender unit seal four times before installing the tank back in the truck because I didn't want to deal with any leaks, so I really hope it's not that seal. I also filled the tank up to the brim right after install and crawled all around it a day or so later and noticed no dampness or leaks. Needless to say, I'm not looking forward to dropping the tank again and then potentially waiting on parts if something is defective. I'm waiting on a call back from Titan to get their advice.
Below are a couple pics of the weepage. Obviously not a huge leak, but something I want to get taken care of ASAP.
The check fuel inlet light went on. Should we be concerned? What does this mean?
View 9 RepliesThe leak only happens when filled more than 3/4 of a tank. It appears that the leak is coming from a hose or hose fitting to the right of the opening on top of the tank,under the driver's side rear seat. So far I have only been able to drop the tank about 2 inches.
View 3 RepliesNew to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.
My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?
Is it bad if there is oil coming out of the valve cover breather going into the turbo inlet? I noticed the sides of the turbo inlet on the top is lightly covered in oil.

View 10 RepliesI am running into some issues with my 2011 Escape 2.5L. I am pulling a total of 7 codes. Two codes keep repeating, which those are P0455 and P0457. And I am also getting a C1963. Accompanying the engine codes, my HUD is displaying "Check Fuel Inlet" when I first turn the vehicle on.
View 10 RepliesThe computer apparently calculates the fuel economy per trip (or a series of trips if the car is stopped less than 2 hours) but I don't know how to get it to display the fuel economy for the tank full. Normally I'd reset the computer upon refilling but since it calculates per trip it doesn't calculate per tank. Fortunately the fuel gauge seems to be pretty accurate and each mark is approx 1 gal so I can do a quick approximation but I'm used to having the car do the tankful calculation. BTW, I reset on MFA 1, I've never reset on MFA 2 and that doesn't show tankful economy either.
View 3 RepliesSo yesterday I was driving home from work.. I know my tank was 3/4 full. All of a sudden, my low fuel light came on and my gas gauge needle went to empty.
The needle sits at E, but it still says about 20 miles till empty on the MFD. When I left the house this morning, it said 5miles till empty.. by the time I got to work, it said 20. Kinda odd..
I will hook up the vagcom when I get home tonight, any area I should scan for? or just a complete scan? There is no CEL error on the dash though. What I could look at to fix this?
Bought a used 2000 Jetta, 2.0L AEG engine by the looks of it, 188k miles. Previous owner told me he did a bit of work on it, and acknowledged the coolant leak - have to fill the overflow ball about once a week. He said he recently replaced the timing belt, water pump, and tensioner pulley. Not sure if that has anything to do with it.
From what I can see it seems to be leaking at the outlet flange (see pics of rust).
Would any of this cause the water in the overflow ball to be rusty yellow (see pics)? Should I just go ahead and replace the ball and then the o-ring at the outlet flange?
I'm new to VWs, but am up for a bit of work to make sure it gets to 200k miles (bought the Bentley manual).
The truck has been a dream for several months and I had a coolant leak at the thermostat outlet. Changed the fitting and thermostat and sealed with lots of blue monkey snot. It's been perfect for a couple months but a week ago it started leaking again. Exactly the same as last time. I cleaned the mating surface of the water pump with a plastic scraper to remove the old sealer and then finished it with fine scotch brite. I looked at several parts breakdowns and none of them showed a gasket.......
View 14 RepliesAs some may remember, I had a new engine put into my B6 about 2 weeks ago. Everything had been great since, no rattles, squeaks, or check engine lights, until tonight.
About half an hour after I get home from work, my wife heads out to a meeting. She opens the door to the garage and is about knocked over with the smell of fresh gas. NOT GOOD.
I tell her to get in her car and go, I grab the flashlight and pop the hood on the B6. Low and behold, the middle gas line of the 3 lines on the front right of the engine had come completely off! It was leaking gas everywhere and directly on to the alternator. On closer inspection, I notice that the tech. when he put in the new engine, he NEVER PUT THE 3 HOSE CLAMPS ON THE GAS LINES!
They were still on the hoses, just backed off from the ends a couple of inches. Needless to say I fixed the situation, but the Service Manager will be getting a call in the morning. This could have been a very very bad situation. I didn't smell any gas on the way home. I hate to think what could have happened.
