Will the F-body Hot wire kit wortk in a truck with a returnless fuel system. Is there someone that makes a kit that will? And would it be worth doing for a boosted 6.0 (8-9lbs) with a walbro 255 in-tank?

 

The F body kit will work. I used one on mine (04). You just have to splice in the correct plug on your fuel pump module. All the wires are the same, just the physical plug is different. Easy fix. Great upgrade for a boosted combo.

 

Cool, would it also work well if I add a magnavolt later? I think that may be the answer to the returnless system if I start to run out of fuel when in boost.

 

It should. I'm going to use a KB BAP when the time comes.
