Sometimes a tool is a matter of a specific need. You guys that build or otherwise play with GM motors know the old trick of driving the oil pump on a SBC with a drill to pre lube the motor. No such luck with an LSX series motor. I've used a hand pump in the past but wanted something better, easier. I saw this in a magazine article on line some time ago and built one for myself.
It has a SBC oil pump mounted under the lid, driven with a common driver shaft for the same oil pump.
Drilled out a second drain plug and tapped it for 1/8 pipe
