I have a '97 PSD and I have a vacuum/pressure gauge that came with the kit I purchased from GoldenFuelSystems.com
I am wondering if you look at the gauge only when it is at idle or all the time.
My gauge reads 12 psi of pressure at idle which is what I was told was great.
The pump I have is rated to kick out between 5-15psi. It is just a small little fuel pump right after my Racor filter. Check out pics.
However, when running down the road lately I have seen the gauge drop to -10, thats 10 psi of vacuum.
However I am running 80 mph and pushing down on the throttle.
I just did the FPR shim on my '97. I would have thought that would have given me more psi
Also, I just changed my filters, stock and Racor 2 micron filter.
Another question, Do I need a higher psi pump for my stock fuel pump. Mine is a mech. lift pump. Whenever I switch over it has a psi of plus 10 at least.
Thanks,
Fletch
