One important note EFI pumps like to push fuel, but are very poor at sucking - so the pump needs to be below the fuel level and as far back as possible. Some times the factory will put a low pressure boost electrical pump ahead of the efi pump to ensure the efi pump gets the fuel out of the tank. Look under VW jettas/golf's for this type of setup.
now this I will need to work out. My current line has a up hill run before it gets to the filter. I have the stock mechanical pump for the carb which does fine at sucking the fuel from the tank all the way behind the rear axle. A rerouting of my fuel lines looks like it will be needed. I also will have to see if I can raise my tank a bit.
I was also thinking of rotating the tank so the outlets are pointing towards the rear and mounting the pump on the frame to the side of the tank. I might use some 1.5" square tubing and cut 4 blocks so I can raise the tank up a little bit.
