fuel pump pressure

<< < (2/2)

quadrajam:
10-4 sounds like you've got it covered. good luck.

Radiator in the BACK!??! I love the idea of that.
Until recently I had problems with excess underhood
heat and considered doing the same to my 92 s10.

I have a 1965 corvair with a 1976 caddy 500 ci in the front of the car.No room in the front so I put it in the back under the original vents. Took a lot of time and effort.

von:
The cheap Airtex fuel pump I tried years ago put out 9 psi running and the '69 Q jet tolerated it ok while running but when the engine was shut off is when the flooding problem started. The heat soaked engine would cause fuel in the lines to expand and pressure would spike up to about 11 psi. Fuel would flood the engine and make it hard to start. A new AC Delco pump fixed it.
