Re: 65lbs fuel pressure but only for 2 seconds

If you have the fuel pump module out, there's an easy way to test the check valve and flex line. The 3/8" fitting on the pump module is the pressure line. Slide a piece of 3/8" hose onto the module fitting: you should be able to suck on the hose with very little resistance, and you should NOT be able to blow into it, at all! If it fails this little test, replace the module. I check every new pump I install, before I install it.
