Hard start or long crank times after unit sits overnight,also intermittent,may go a week no issue may show issue after sitting a couple of hours...then when you pressure suction side of system you find no fuel leaks because the pressure helps it seat and seal...357,748 man hours of troubleshooting later you through Mr Compucheck in trash and SHAZZAM problem fixed!

Why would you want to put this on your fuel system? I can see off the compressor where many of us have them, or on the radiator for quick drainage, but on the fuel system? Am I missing something?
