I have determined I need to replace the manual fuel pump on my small block Chevy 350. I am running a Holley 670 Street Avenger carb. I have looked at what is available for my engine and see that the prices range from $90 down to $43. I am considering the Holley 80GPH pump. But the Summit or JEGS brand appears to be the same and is at least $20 cheaper.

Does any one have experience with these store brands and are they worth a try? Should I be looking a 110GPH instead of the 80? What is the most dependable brand?

The pumps I have looked at:
Summit (80) $43 / (110) $53
JEGS (80) $45 / (110) $55
Holley (80) $64 / (110) $72
Edelbrock (110) $90
Carter (120) $72
Mr. Gasket (80) $60
