efi to carb
which engine? I6 5.0 or the 351?
i don't think it would be worth it to swap the I6 to carb or any of them as far as preformance goes but the 351 and 5.0 might be worth it just to delete the maf set up

It's not that bad there are a couple of ways to do it one is to go with a low pressure regulator with a bypass valve and a larger return line and use your existing fuel pumps.
Or swap out the pumps with the older style pickup assemblies and use a manual or aftermarket electric fuel pump.
While I was at it I would also rip out the old ignition system and dist. and go with a MSD or other simular type system.

just curious why do you want to go to carb? the regulator should be cheap. just make sure you've got one that is for whatever your going to use for the pumps.
I have one that takes high pressure and converts it to carb pressure and then adds 1lb of pressure for every lb of boost I toss at the motor. But it's like 2bills in canada for that plus the fittings.

The regulator is not cheap the one I saw that was made for this conversion was around $140 best as I can remember.
I went back and checked this is a different one but cheaper

If you dont like the FI systom on these trucks then you are realy not going to like the carbs especialy the electronic feed back carbs used for prier years. OH and for what its worth if it matters the guy at the smog police are going to like it even less. But do what you gotta do Bubbabud
