Eddy 1406 pissing me off (LOL)
Before I went with EFI the best things I did on my 67 were
electric rear mount fuel pump and garbage can the mechanical
install a vapor return system with Wix fuel filter with return port, 33040 / 33041
and a nice thick insulator
The problem might be "more" Ed than Holley, but remember, thousands of AFBs were used for years and years on cars, before we had alcoholized fuel. I'm not just talking Mopars. AFBs were used on GM and Mopar
