I used the carbed truck tank for the ease of not fabing up a new filler or having to do any mods to my freshly painted body. If i can find a 22re longbed tank i will be grabbing it and having a fuel line made. The hard part is i moved my fuel lines over under the driver side so it was across the truck from the cat and piping. The line that runs from the lines to the tank is kind of a pain in the butt to have made. I have a few more places that may be able to do it when i swap over tanks.
My other thought is mod up the feed on the carb tank to put the efi pump in. I have the stock tacoma tank i can use the pump and sending unit in the carbed tank....Im thinking this may be worth an attempt.
