I just recently installed a surge tank and a couple bosch 044 pumps. I removed the fitting that came on the outlet of the pumps. I was wondering what my fuel pressure should be with the car off. My fuel setup is :
aero 340 > surge tank > dual bosch 044 > aero rail > aero fpr > surge tank > fuel tank.
I had all of the other fuel stuff on the car already. I was wondering if my fuel pressure should remain the same when I turn my car off (38-40 psi). Before the install, my fuel pressure would remain at 38-40 psi when I shut the car off. Now I can see the needle go back to zero when I turn it off.
