The pump will need to be eliminated. Carbs like 7psi, injection likes 40psi.

Personally, I think swapping in a carb is going 20yrs in the wrong direction. A TBI 350 is super easy to put in. On the trail, injection wins. Get off camber or up a steep incline and you will see the problems with carbs first hand. Injection will run standing almost verticle, a carb will spit and sputter.

Anyway, the carbed 350 should have a mechanical fuel pump on it, so all you will need is to get the supply line to the bottom of the tank. Not sure how you would go about doing that, but that's all it should need.

ok thanks for the responce. Im going with a carb because i am a fan of them and absolutly hate working on the newer stuff. i figured the pump would be too much for the carb but wasnt 100%. also i was looking at the holly carb that is built for off roading.
