i have sm 376 and what gallon per hour should i get. also what psi.
I am not sure what an SM 376 is, but if you are running carb like in your profile, wouldn't a stock AC Delco fuel pump work for you? Edelbrock and Holley also make mech pumps that are rated at higher gallon per hour too if the AC wouldn't pump enough.
the sm= small block
That is what I was thinking, but I have always seen:
as designations for small blocks. Are you running an electric pump or manual pump right now? How many PSI & GPH? How high performance is your motor and how much of both does it require?
If yur running a Q-jet the stock AC Delco pump should be fine.
Go to autozone and get a new one. $14 and lifetime warranty. I've had one for three years, no trouble!!
I have to agree. I have a stock Qjet on my 350, and the AC Delco pump supplies it fine. The last fuel pump was on my truck for over 3 years. It went out and I replaced it with a new AC Delco about 3 months ago. No probs sofar. I do carry a spare just incase, but that is just me. I am crazy like that. I carry spare everything.
i dont know about the auto-zone fuel pumps. I've gotten a bad fuel pump or two from them. and their rebuilt carbs suck too. but that is just my experience.
