Mallory Electric Fuel Pump/Fuel Compatibility

Holley bought Mallory, and then did their best to destroy it, by doubling or tripling Mallory prices (to improve holley fuel pump sales)(and the current Mallory ignition stuff is re-branded msd, also holley) I agree, with all the alcohol in pump gas now, the alcohol kit is a no brainer. Even if it weren't 25% the price.
I also like keeping your Mallory running, so you don't have to buy a holley pump.
My 20yr old Mallory 250 reman is going strong, paid $50 (maybe it was $75). That pump now is over $600.
