It's aftermarket. I have not actually bought them yet, but was planning on buying this fuel pump and while I am in the tank, I was also planning to replace the fuel filter canister with this one.
Both are aftermarket replacements for the actual Harley partnumbers.
Good idea or penny wise pound foolish?
I'm with dolt on this one, I'm not a big fan of electrical aftermarket parts. Changing the pump is no small task as you are finding out. If it were me I'd opt for the real deal. JMHO.
