Quick question. I am upgrading my entire fuel system to be at least 15 -20% Ethanol resistant, so I'm not restricted to just Shell 91 gas.
The Holley Street Avenger 670 is ok for 15%. All engine bay hoses are replaced with EFI high pressure somewhat ethanol resistant. Next is a new fuel tank from Spectra Premium ( American Designers, Canadian made) that is good for 20% and new hard lines to the pump.
Here is the question, Does anyone know for sure what brands of mechanical fuel pumps are available that have ethanol resistant diaphragms in them for the 351C? Also, the hard lines. 3/8" I think, need to be treated steel, or stainless?
No need for a long discussion, I just need to know what to buy.
Thanks all,
Geoff.
