engine and drivetrain Electronic fuel pump advice needed

[schwarz75]

Wanting to replace the external fuel pump that's located behind the rear axle next to the gas tank. It's a Carter style. Looking on Summit Racing's site I find a few that will mount exactly like the fuel pump on my 2002.

(1) 5 psi & 72 gph (Airtex)

(1) 6 psi & 43 gph (Carter)

(4) 6 psi & 72 gph (All Carters)

(1) 7 to 8 psi & 72 gph (AC Delco)

This 2002 has twin 45 Webers + an adjustable fuel pres. regulator, set to 3.5 psi. Engine is 2.2 liter M10 Stage III

I had an airtex with the same engine setup. worked great.

i used 2.5psi at the AFPR.

Thanks Marshall.

My advice is to use a regulator and a gauge no matter what

pump you choose.

I have yet to find one that will deliver less than 4psi.

And the Webers are happiest at 3 or below. And consistency.
