8.1l Fumoto valve

[70ChevelleSS]

Anyone know offhand which fumoto valve fits the GM 8.1l engine? I'm sure I could figure it out but I'm also sure someone here has installed one on their engine.

Thanks in advance.

I searched for 2002 GMC 8.1L and it gives me this:

Hank,
A quick call to your local GM dealer, to the parts department, would put you in contact with a parts person, that could simply look up a new drain plug for that 8.1. The information would more than likely, also reveal the thread size and pitch. With that info, you could proceed to procure the correct Fumoto valve for your engine. Just a thought.
