Be careful in using one of these transfer pumps. I hooked one up to the inside of a gallon jug of gear oil for the Toploader, and the other end to the filler hole of the transmission. It started out working fine until the gear oil started to get pumped out the exit. The pressure proceeded to blow the lower hose off the pump, and the oil splattered all over my nice clean shock tower, aprons, and firewall. Yeah, I was a little PO'd. I then tossed the pump and used the 1 quart jugs instead through the lower hose, squeezing them like toothpaste.
