Can anybody tell what the correct fuel pressure should be on a 1995 Astro van with a 4.3 ?
Thanks Dave.

60 - 68 PSI, IIRC .

Welcome aboard!

According to chilton it should be 58 -64 psi on CMFI engine key on engine off and decrease 3-10 psi at idle

Thanks guys
I was told it was between 9 - 13 lbs. I have a constant 13 lbs. That's going to make a big difference!! Out comes the fuel pump!

WAIT!!! do you have the vortec intake or TBI?
vortec intake is 58-64
Throttle body injected is 9-13

Thanks for the heads up zombie!!
When I ordered the fuel pump it was by the VIN so the dealer knew the right one to install.... which was the one for a "Vortec" engine..

Thanks to all
Dave.

BTW it runs great now..
