PS leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I got my truck on the road last fall and all was well but all of a sudden I notice a puddle of ps fluid under it. Hard to tell for sure but it seems to be coming from the big nut on back of the pump. I think it's behind the nut leaking not where the fitting goes into it. The big nut I robbed off a square body pump (pre 81 sae) to use on the LS pump. Is it supposed to have a washer/seal/o'ring of some sort? It's going to be a *#^* to work on it. Pretty tight in there.
