440 fuel pump

[bridjet]

Hey guys, I’m new here and Im having a hard time deciding what mechanical fuel pump to buy. I have a 67 Chrysler 440 engine bored 30 over with a Holley double pumper carb in a 73 Sebring plus. It will just be a street driven car. There are several pump options and I’m not sure which is best with my set up given I won’t be hitting a track. Any help would be appreciated!

For a mechanical, I am using a Carter M6903. I think it is well made, rebuildable, and supplies ~6-7.5 PSI which is not too much for the carburetor without return line. I took mine apart when I bought it to clean up threads. If you are just driving, my a standard one from the autoparts store will be less expensive and work fine. I used one of those for 40+ years with few issues before getting the present one.

Carter M6903...yep, best bet.

I also have the reproduction "hemi" Carter M6903 on my 440 right now, works fine.
I also have a couple of like new "parts store" pumps sitting on the shelf and truthfully, for this fairly mild engine,
they'd probably work too.

Let us know what you think, and don't make the same mistake I did-be SURE to flush your fuel pump and pump to carburetor(s) lines before you hook up the upper fuel lines to you carb(s).
