Here's another way to do it with external electric pump. This is the tank I am putting in my 46. My plan is to start off using the sump hooked to the engines fuel pump. Then, if I ever want to switch to EFI, I already have the scavenge sump built into the tank.

Here's a bad pic but you can just barely see the supply nipple coming out of the sump.
