Hey I put a new fuel pump in my truck had 60 psi
ran great for 3 days now it want start. I checked
the psi now it's 40 psi .
I suspect the spider injection is leaking and would need replacing. Put the fuel pressure gauge on there, build up fuel pressure, then turn the key off. Fuel pressure should not drop more than 5 lbs. in 3 minutes.
