HUGE drop in FP ?????
This time last week I was 13 @ idle 11 at cruise and 7-8 @ WOT
Today 9 idle 7 cruise 5 WOT
I have a little dead pdeal right when i start and have seen the P0216, I know the VP is on its way out in a hurry, and with info Im assuming the LP is not far behind it, if not in front of it.
Thanks
Jamie

make sure you have fp above 8-10 psi (minimum) at WOT at all costs.
do you have a fp guage?

I recently took my truck in under warranty because I am 12psi idle, 8psi cruise and 4-5 wot. They said they would put in on diagnositics. After 2 days they said fuel pressure is within toleration. They said they would replace LP or FP when needed. I am back to driving with same PSI readings. Frustrated but dont know what to do. It runs fine other than PSI seems low. What can ya do.

Well I had a dead pedal today for about 5 miles and once it started working again I was cruising at 4psi and could drop it to 0 at will.
When I replace the VP I want to get a comp instead of the EZ, what pump do I need to go with in the Vulcan Kit I have, would a holley blue flow more than a stock LP?
Thanks

blackdiesel,
I have a fuel pressure gauge. I installed it a few months ago. I'm at 14-15 idle and 12/13 cruise and 10/11 WOT. I'm keeping an eye on it.
thanks,
Bobby

Why would my pressure be different during the day? In the morning when it is cool, I get 13 at idle and 9-10 at WOT. In the afternoon when it is 105 I am only getting 9 at Idle and I can pull 3 at WOT. Is the heat messing with my gauge? I am putting on a second pump this weekend, I was just wondering if heat has an effect on FP.

Thanks, I'll just do what I can to keep it up above 10 PSI...I will be running a Holley blue in line with a carter pump both off of relays...till I can buy something better.
