On my 78 L48 there is a plug that threads into the top outlet of the pump. Does anyone know the specs on it (size)? I need another one and need to know he size.

Thanks,
Dan

just buy the 2-3 that look close at home depot or lowes. I just bought a plug for my intake manifold this morning, but can't find package plug came in to be able to tell you exactly. get the galvanized, they are cheaper, then bring back the one's that arent right
