SOURCE: Rear fuel line at the tank is leaking

The connection is a quick dissconnect, I unpluged the line by pushing up on the bottom of the fitting and pulling down on the retainer . This allowed me to unplug the line. I then removed the fitting that was threaded into the tank and found the rubber "O" ring was bad, I replaced the "O" ring and put the parts back together. ( i sprayed a little WD 40 on the Quick dissconnect and applied a small amount of "O" ring lube to the ring prior to putting everything back together )

Replace the petcock. The rubber diaphragm is ruptured. I'd also bet your fuel mileage dropped cause the ruptured diaphragm is allowing raw fuel to be sucked into the intake manifold.

How to set idle


It could be just a lean idle mixture. Even though it's injected it still needs air. Nothing to adjust timing wise. Sometimes a fuel leak inside the fuel tank on injected bikes will mess things up. They have fuel pressure lines in there. If something is leaking you'll get lean or no fuel at all. There should be an in line filter. It could be restricted. There could be a crack in the aluminium fuel line part, when someone puts too much force on it, while changing the filter. It leaks into the fuel tank so it go's un noticed. You may be able to see it jetting eddys in your fuel, like a current of water.

Leak injection pump


Sounds like you are going to have to drop the tank out to inspect and fix. with luck it will be leaking from the fuel pump seal or the return line. If your truck is fuel injected , and the pump is in the tank , regular fuel line hose won't do, need to buy stronger hose rated for fuel injected cars. If it is the return line, won't be as high presure.

I have a 1989 f250 with a 7.3 90k on it a/t no tubo if it sit for 6 to 8 huors some time starts up and then dies it acts like the fuel is gone and it take alot of cranking to get it fire up but it runs...


It sounds like an air leak in the **** side of the pump, it can cope with some air when running without any misfire, the fuel will run back to the tank after time and need re priming. Has anything been changed in the fuel system lately?

I have a 2004 sequoia that leaks gas at the passenger rear/ area under tank has a round pipe where the gas is coming out. Only leaks when the motor is running.


possible crack or damaged fuel line, fuel injected vehicals are high pressure (unsafe to drive if leaking). also check to see if fuel filter is leaking fluid.

Engine turns over on my 2003 Jetta 1.9L TDI but does not start. New battery , all lights are working. Changed fuel fillter and put diesel in it to wet it, but still does not start. It did start once and...


When were the glow plugs last changed?

They sit over the cylinder like spark plugs and warm the diesel before it goes into the inlet manifold, greatly assists starting.

Car lazy to start


Hey bro, your diesel pump might be on the way out but here are some things to check and do and see if they help.

Replace the hoses going from the pump to the diesel filter with new ones.

Use fuel injector type clamps, NOT gear clamps they don't tighten enough to stop air not getting in.

Change the diesel filter, and make sure the drain on the bottom of it, if it has one which most do, is nice and tight.

Air bubbles in the injection lines are usually a sign of a weakening injection pump but I ran mine like that for a long time, the air works it's way through. Are you leaking any diesel? Maybe check the returns to the tank. Cheers bro.

Cannot get fuel to come out of tank to carb for starting. have trx engine 3.3 in a revo model 5309.tks engine will run if you inject fuel directly into carb.


Could be an air leak or seal problem with the fuel tank. One fuel line goes to the carb, the other line that goes from the exhaust pipe to the fuel tank pressurizing the fuel tank so that fuel will be forced to the carb. I would check the fuel lines and tank for leaks. The tank can leak air around the lid or a seam in the tank itself. I would also check any inline fuel filters for blockages or leaks also.

Strong gas smell when engine is turned off.Car runs smoothly otherwise. Started doing this abruptly. Of course milage is now suffering


Hi,
This sounds like a problem with the "Emissions control system"
Designed to absorb fuel vapours - and release them when engine running, When they go wrong it leads to excessive fuel consumption, fuel smells and possibly leaks.

It is most likely a split pipe along this system - which needs checking carefully to find out where exactly.
Overfilling of your tank can lead to pressure problems - popping off a hose, so if you remember doing this - check any carbon filter element and hoses around it.
