First I should note that that was a Kit version of the skybolt. There is a space under the front of the tank forward of the landing gear that is covered with sheeting. I removed the sheeting and that where the pump went.

I then moved the tank back into the radio compartment, and added an 8oz tank where the tank normally sat.

The engine was a YS 91AC, so moving the tank back was no problem for fuel draw.
