Clint, before putting my V8 Monza on stands I was using an electric pump w/ no fears. Maybe a different brand may help.
I completely understand your distrust in them, though, and here is the link to the mech pump frame cut-out Merle is talking about:

You may know this already, but when using any type pump, mechanical or electrical, it is a wise idea to make sure you don't exceed the max psi input to the carb. For example, you don't want to exceed 9psi into a Q-jet.
Anyway, very sorry to hear of the woes on your Power Tour, and after you were looking forward to it so much, too.
Hope all goes well from here forward. Good luck.
Very nice TC, BTW.
cheers jer
