Hey guys, i keep having major problems with my fuel system, and i cant figure out whats wrong!! I have a 97 wrangler sport 4.0l with 5 speed. and original fuel pump.
First symptom was the hard starting. So i installed a check valve right after the fuel pump.
Then my fuel line going to the fuel rail popped off (nylon to metal part), i replace that and it was good for a week.
Then my nylon fuel hose after the check valve sprung a pinhole leak, i changed that, all was good.
Next few days, i smell gas, its in the engine side again, my 2 fuel injectors were leaking, so i replaced all the o-rings, but one injector still leaked. I got a replacement from the junkyard, and replaced it. No problems for 2 days.
Then my rear nylon fuel hose sprung another leak!! The hose just blew out! So i replaced that, again.
Next day, i smelled gas, again. This time up front, another fuel injector leak, but this was the main body leaking. So i replaced another one.
Now, everything is ok, but i have a feeling i will have another leak! Any ideas on what to look for to remedy this problem, or am i just having a string of bad luck!
