Any tricks for finding a leak in fuel line ?

I fixed it !! You’ll never guess what was going on , so first I bought a fuel filter and some nice fuel injection rated hose clamps and about 7 gallons of gas. I took the sending unit out just to inspect it one more time and guess what I discovered … the sock filter on the end of the pickup was literally sucking down onto the end of the tube because the top and bottom of it were plastic and the sides are mesh ….. I cannot believe that someone would put this on their car and not think twice. With the sock pulled a teeny bit off of the pickup it works just fine but I sucked through it simulating a flow of fuel and it slips right back almost completely stopping any fuel flow . I removed that put the sender back in and I put a clear fuel filter right at the tank and started it up , not a single stall or hesitation and I drove probably 6 times farther then any other test drive so far , only thing is it has kind of a hard start when it’s warm and also I need to turn the idle down because it’s getting WAY more fuel then it’s used to.


Thank you FABO for all the ideas and conversation it helped me so much throughout the process and I really appreciate it u guys are awesome , now I know to check the parts that aren’t broken for crappy design haha
