My FE dry sump pump was manufactured by HW...Fresno, Ca...at least that is what is stamped on the pumps.
This dry sump has an internal dual pickup
oil pump which scanvenges
oil to an external tank. The internal
oil pump is turned by a shaft connected to the distributor...like a regular oil pump.
Inside and at the front of the oil pan is a sprocket which turns an external pump. My question is...how is the sprocket which is inside the oil pan, driven. It seems logical that a sprocket on the crankshaft meshes with pan sprocket.
