Mallory Electric Fuel Pump/Fuel Compatibility

Thanks John. I tried calling them, but you know how that goes. I can't think of any reason an alcohol-compatible o-ring wouldn't work for gasoline too. My pump gas has ~15% ethanol anyway, so it's probably the one I want anyway.


Use the cheaper kit. If it will take alcohol it will take pump gas.

Calling MSD (actually Holley) is useless. They are F’ing worthless. It’s disgusting.
