i have asmall leak on the drivers side just in front of the rear wheel on my 90 integra. only when under pressure. I just bought the car. seams like from the tank. whould it be the tank?

 

The only real way to test this would to pul the gas tank and do a leak down, but i guess what you could do, is remove the drivers side rear wheel, and put a pan down there over night, and see if any leaks out.

Hope this helps.

 

Sorry, that doesnt really answer your question, but i guess this would be the process of elimination.
