I think i might have a leaking injector because I just put a new fuel pump in and its running at about 42 psi now instead of 30 psi but know my car runs really rich so rich i was throwing fire balls out the exhuast yesterday. when i replace my pump i re placed it with a walbro 255. I noticed a couple of days after i replaced the pump when i put my fuel pressure guage onthat after the car sits for about 30 mins it bleads down to 0 thats what makes me think i have a leaking injector plus how rich its running. What you guys think

Easiest test first.

Prime the car and block off the return and feed line at the fender where they are rubber.

Should hold pressure.

If the pressure drops, u might want to go further and repeat the test with the fuel rail pulled up and clean paper towels underneath them to identify which one is dripping.

later

Ok I tryed the test and no matter if I block off the return or inlet it still drops i can sit there and watch the nedtal on my guage drop so i guess i will need new injectors I think i will go with so 24lb for future mods
