Don't worry about priming the pump. All you can do on our motors is crank it with the ignition and fuel pump disabled. We don't have a distributor shaft that we can stick a rod down like other vehicles.

As for petroleum jelly, it's not needed unless you're installing a dry oil pump assembly. It basically lubes and protects the gears until oil flow takes over. The heat will melt it and make it merge with the oil after the engine gets to temp.
