I just installed my ISSPRO Fuel Pressure gauge. At Idle it is reading 7 1/2 PSI. I bleed it again and it still seems a little low. I have replaced the Filter. It's been about 10,000 miles ago. I should have another 5000 miles to go. Is my lift pump about to die? They did just replace my CP3 pump in January 06.

 

That sounds normal for the 3rd Gen if I'm not mistaken.

 

Your lift pump may have been starving your cp3.

My next mod is a fuel gauge and then an aftermarket pump of some sort. I was curious what they were running stock, and I am guessing yours is probably normal at 7.5.

 

6 to 8 is the normal range.

 

Yup. Mine started out at 8-9psi and within a couple months I was down to 6psi. That's when I knew it was time for the FASS. Now I'm at 18psi.....
