On the issue of the fuel pump, I did see someone (think it was Stovebolt)
that sells a fuel pump hole cover plate, so that you can install an electric
pump. If that is all that is wrong with the cam, do it; taking the cam out
& replacing the bearings takes a special bearing insert tool & either the
engine needs to be out of the truck or the grill removed for frontal access.
