My 90 RX7 GXL has a small gas leak that appears to be coming from around the front left of the gas tank. The leak is small, leaving a small puddle of gas under the car after sitting overnight. I haven't looked under the car yet, but I'm suspecting that the leak is coming from one of the rubber fuel lines going to the tank. I am the original owner of the car, and have never changed any of these hoses. There seems to be a lot of plumbing back there due to the gas supply and return lines, check valves, and so on. Before I put the car on the lift, I'd like to buy fuel injection hose but am not sure what size hoses are back there. I think it's 5/16" -- Is this the right size? Has anyone had any similar problems, and can perhaps point me to the potential trouble areas back there?

Thanks,

DO NOT DRIVE THE CAR until you find out just where the gas is leaking and fix it..... any farther than that I can't help ya.

I been driving my Acura ever since I discovered the gas leak. Although the leak is only a small drip at this point, I didn't want to take the change of a high pressure fuel line rupturing while I was driving. I bought some 5/16" fuel injection hose yesterday, and am planning on getting the RX7 on the lift to fix the leak. Hopefully, 5/16" is the right size hose.
