If fuel pressure is goid, check for vacuum leaks

85,435

Fuel pressure should be 56 to 63 lbs. at the Schrader valve up on the intake. When doing so once the fuel pressure has built up turn the key to off, watch the fuel pressure gauge. It should not drop more than 5 lbs in 3 minutes. If it does, then it is an indication that the spider injection is leaking.
