After looking into e-pumps, they all say to mount below and close to tank as possible.. Umm okay, I guess I'll just slap this pump onto the axle since this seems to be the only spot that's below tank
I thought I could just have it sit inside the frame rail, but that only gets me halfway to the bottom of the tank.. other options, I could drop 400-500 on a self priming e-pump, but I'm not really feeling that idea.
