mechanical fuel pump to electric

[echappe]

Can anyone tell me what the pressure and flow specs (PSI and GPH) should be when sourcing an electric fuel pump for the 3.5l coversion keeping the 32/36 weber carburetors.
Thanks in advance for the help

Pump Specs for Carbs

You want a pump that has 3.5- 4 psi min; maybe to 5. delivers about 15 gal/hr. Preferably one that doesn't require a regulator. ( Another part to buy and space to put it.)

Pulse type pumps are fine, perhaps a bit noisey for some- cost about $35/40. Rotary costs a bit more, maybe twice but quieter- about $60-80 if you shop around.
