I'm using a 45DCOE Webber carburetor on a 12A. I have a fuel pressure reg on it, but on the upper rpms I lose pressure. Can I use a Holley fuel pump that holds a constant line pressure of 4psi or can I get away with using the one that holds constant 9psi? In this case, is more line presure better? <_<

i find fuel pumps really confusing, if you have a regulator than a 9 psi pump is ok, but you are looking for flow.

I used a Holley Blue on my Weber 48 IDA and had no problems. B)

I use a Holley blue on my 600 double pumper and have no problem getting fuel to my carb..im running 6 psi..also

Cool, thanks for the info. https://www.nopistons.com/forums/pub...O_DIR#>/37.gif

Carter fuel pumps are nice and I would recommend them.
