Anyone know what pressure and volume the low-pressure in-tank fuel pump puts out that Ford used from '85-'90ish?

Doesn't it say in the repair manual? You try calling the steelership and asking them?

Huh, who knew that Napa would list the specs online...

24 GPH
5 psi

High pressure in-line pump puts out 33 GPH.

Looks like that Mr. Gasket in-line fuel pump I installed in an emergency when the in-tank pump failed will be there to stay. Specs for that pump is 4-7 psi and 35 gph.

Whats the high pressure PSI spec? I know the rail is 35-40, but the output of the pump must be significantly higher than that.

Napa says 44psi online, but I'm not sure thats right.

so if i wanna convert my truck to carb and use only the back fuel pump, sounds like my carb might get starved... i thought the pumps were like 90 gph
