If its CSFI

Should be 60-66lbs psi and running-not up to standards you have a problem with FPR or a restriction

On SFI 56-62lbs psi running

Thanks for the reply. Are there any aftermarket pumps available with similr performance curves that are not tank mounted? I have replaced this one 5 times since I bought the rig. This drop the fuel tank deal is for the birds.

Lol double check the fuel system test the fuel pressure regulator and check for line restriction-something is wrong 5x Wow!

About aftermarket stuffs dunno-look around in the Net-this injection system is very picky on pressures.

Good Luck!
