Soo I purchased a g35 that already has a fuel tank leak, he provided me with a new tank. I was curious if I can locate the leak and patch it up for the time being until I have the time to either install the new tank myself or have a shop do it for me. He said it starts leaking just over a quarter tank and I currently have less than 10 litres in the tank. Should I keep filling gas into the tank until it starts leaking? What is the best approach I should take to this situation. Thanks

 

Remove the back seat, there are two pull tabs right where the seat meets the carpet in the middle of each seat. Pull both to the front of the car and lift the cushion up at the front. Now there are two access panels, remove and see if it's leaking from the primary line.

If not then get the car up on jackstands and see where the fuel is coming from.

 

soo here is what I got when I opened the access panels, since the leak isn’t coming from both access panels, should I just buy some gasoline so it leaks, and then I can find out the location of the leak under the car?

 

Yep that's exactly what I would do.
