Hi All,

Ive been working on the car, tuning what have you not. I went out for a spoin with Mike K, we determined my issue may be from a bottleneck in the fueling system.

Things I need to check.
1. What should the voltage at the fuel pump be?
(right now I have the ZZP pump rewire kit.) How do i effectively test the pump, if bad ill go with the wbodystores unit.

2. I know the fuel pressure should be 50 reg, and up to 62 psi at wot. Is there anyone in the Northern IL area that has a Fuel pressuer tester, gauge? I have PRJ rails. Is that puel pressure correct?

3. Oh yeah, Ron, can you post the part numbers for the 38lb injectors and place to buy. I searched your posts and have one that has a place, I just wanted to verify. Last posted,
I found 2 Lucas PN's that will work, and are safe:
8f160-038 (38#/hour)
8f160-042 (42#/hour)
Both are rated at 16.6 ohms
Once I have my fuel issue figured out, a 2.75 will go on, and I will need bigger inj's

4. New fuel filter... maybe its clogged...
