R32 Gtr Fuel Leak

[Godzilla82]

Hey all

I had two fuel leaks on my car. One was the injectors and the other was at the back of the car. I've recently replaced the injectors so now there's no longer an issue there.

I'm not quite sure what is causing the leak near the tank, a mechanic has told me that there's a small hole in the tank but I noticed that the whole tank is covered in fuel above where the supposed whole should be.

The car sometimes needs a bit of gas to start and when it does start the idle starts very low and then slowly builds up also the idle is a bit rough after I replaced the injectors. Also I'm pretty sure the leak only happens when I drive it a bit hard and it doesn't seem to accelerate fast enough and once it was jerky when I tried to plant it so I'm thinking its the fuel pump.

Any thoughts?

sounds like 2 issues.

1. possable fuel pump

2. Maybe the cap at the top of the tank has been removed and not put back on correctly or one of the fuel lines in that area hence the leak.

If you remove your carpet in the boot on the drivers side should be 4 bolts around a plate with wiring going into it. If you remove this you will see the top of the tank where the pump goes in. Have a look to see if you can find the leak.

Cheers guys ill have a look. Do you guys think that the rough idle is tied in with this problem or is it another issue? I gave my car a full service yesterday and the idle does the same thing, when I start it it almost stalls and then it very slowly goes to 1100 and whenever its idling its a little rough...

sounds possible that the leak is from the connection from the pump on the top of the tank +1 to opening the access pannel in the boot and taking a look, if its losing a bit of fuel pressure from the leak in the hose that will 99% be the cause of you're rough idle/jerkyness on acceleration.

also, if the leak isnt the cause i'd be checking for vac leaks/ iac valve opperation (idle air control valve)

Just put $50 fuel in and its leaking pretty heavily from the side of the tank. I'm going to check near the fuel pump. Cheers for all the pointers guys. Much appreciated...
