This is the Holley pump I have. https://www.holley.com/products/fue...bureted_electric_fuel_pumps/parts/12-150

I ran it a couple years on my 408 then replaced it with the magnafuel, very happy I didn't sell it. I've been 6.25 @ 110 with it and driven a bunch on the street. Heck I went 6.57 with a old Holley blue pump and a 3/8" line bent like the factory line, still have it too.
