ok guys this kind of goes along with my other question about the carb stumbling. I got 2 fuel pumps the carter 172 gph @ 8 psi, and the edelbrock victor 130 gph @ 13 to 14 psi. The carter is on the motor now. I've heard 2 diferent things as far as which one to use with alcohol. Whats your opinion on it?

i would use the 8 psi with no return that is what I run and have had good luck so far. less to go wrong. some of the guy's i race with thought I was dumb but now are doing it also. I run a fuel log and a little fater than most.

nevermind, i read up on both pumps and the carter is NOT for alcohol, its a gas only pump. the edelbrock is for both.

Not to jump in and answer somebody elses question , but you need a lightweight fuel-pump pushrod anytime you run in excess of 6000 RPM . A stock one wil float out just like a stock valve spring .

Yes you are correct that CARTER pump is a gas only deal. I have heard that guys run them with alcohol tho. I never did. Always went with the edelbrock. I think it was #1711 that you need.
