Summit mech. fuel pumps?

fstfish66 said

i recently purchased the carter mech 120 GPH i think its 7/8 psi,, from a local speed shop that priced matched summit,, 79.00

ive been running the same pump for 11 years, but was time to replace it,,on a 340 blower motor with 2 holly 650,s re worked to 862 cfm each,,

this is a great pump for the street strip for a cheap price,,you will need a fuel pressure regulator with this pump,,,

but i believe they have a 5/6 psi version also,, cant beat it,,

What is the part # for this carter pump? 79.00 is fairly reasonable for a 120 gph pump. ( I think i found it) M6270.

I did alittle checking, i was told a formula for calculating what GPH is needed for a curtain HP, If this is right, gas weighing 6.2 lbs., to supply 450 hp @ 7 lbs. pressure, i'll need 50.6 gph, 55 to supply 500 hp at 7 lbs. I know they rate most all pumps at "freeflow", so i would think an 80 gph pump should support 450-475 comfirtably.
