Fuel leak under fuel tank

[boeing747]

Fuel leak under the fuel tank, probably a hose, although I still don't know where it comes from. How do you change these hoses?

It's probably one of these.

the top of the tank has 2 ports that are under the rear seats. Need to remove the cover hatch too to access. The tops are plastic and the hose bib connection cracks so it may not be hose problems.

Okay . The strange thing is that when it started it doesn't lose any fuel, it's when about 2 minutes pass when it starts to lose and it's a lot I have to stop the engine because it leaves a puddle. I have to check as you say from under the seats to see if I see the problem.

This morning I started the engine again and I didn't lose anything in the tank area yet but then it started to lose due to a hose in the engine area I tightened the flange a little more and I had it for about 20 minutes and nothing at all no longer lose The car was stopped for 1 year, could this be the cause?

Gas is sent from the tank to the injectors ~ 45 psig. Excess unused fuel is returned to the tank. When the car is stopped, the excess fuel/ pressure will slowly be sent back to the tank. Sound like a return line or hose could be a problem and maybe just a clamp. Leaks can also happen at the fuel filter area. Note the top of the tank has a recessed cap and can hold a cup of liquid. A slow leak can take some time before yo see it drip.

Yes, I removed rear seats and metal cover and it was just a little damp. It didn't lose there either when it was on. I lost a lot the first day of starting and now nothing. Maybe the hoses were very dry, but I don't know.

So it was leaking at the tank first then at the engine?
I recommend you replace the fuel lines at the tank and engine just to be certain they won't fail as you start to drive the car more.

If that is . At the first start, it dripped a lot in the tank part. The next day it was already good and it was the engine area and for I now nothing is leaking. The car was stopped for 1 year, maybe the pipes were dry. When I can I will replace them but they are in a somewhat difficult area to access.

Google must have read some of the replies and sent this video on how to fix up a E36 <a href="http://www.youtube.com/watch?v=lE4M1uTHMSg" target="_blank" rel="nofollow">www.youtube.com/watch?v=lE4M1uTHMSg</a> if you get to 49 min you can see what the gas lines look like and how to replace in the car. Not sure where he got the new belt tensioner but he is not in the US.
