I think its more than just installing a fuel pump and some throttle bodies. You have to change the ecu, the wiring harness, i think even the crank is different. i'm sure there are a lot more differences but those are just the ones with the big $$$$ dollar signs. Better off selling your carb and buying an efi. :dunno:

just get a efi tank. It will be a pain in the rear cause you will have find a way to seal it up good and how to get some studs in the tank and seal them with out them leaking. The EFI tanks have threaded inserts in them. Its a little more work than just chopping a hole in the tank.

All u gotta do is look at a efi pump already installed on another firecat, then measure and mark out where u gotta drill the holes. And make sure u dont over tighten is right.

I installed an efi fuel pump in a 440 tank and it wasn't a big deal. Made a template from a firecat tank and drilled my holes in the 440 tank. The fitting for the wiring has to be removed to fit the pump through the 440 filler neck and then re-assembled inside the tank. A bit of a pain but do-able. The pump has to be angled slightly for it to fit properly and I used a brass fitting between the pump and the fuel pick-up hose because the clearance was tight and the hose was getting kinked.
