Hey guys I'm trying to get this 84 C-10 4.8L/4l60E swap finished up but I was changeing all the oils and
found fuel in my oil pan. I am also having trouble with the fuel pump my intake has a return line for the fuel pump. Can anybody help. I now need to buy the AC delco EP-381 in tank pump but can any one give me a reason why i was getting fuel in my oil system. And maybe help me route the fuel lines the correct why if I am doing something wrong.
