Does anyone know what I have to do with te fuel system in order to power my LT-1 in a 53 willys wagon?

I believe you need a high pressure pump like my TPI does (apx 43.5psi), so you need that to begin with, running all new steel lines from the pump to the engine compartment is a good move (3/8" supply, 5/16" return). I have my pump back by tank, with new hose picking up from the pickup, to the pump, then to the IROC filter, then steel all the way to the engine compartment, where it uses the standard IROC hoses/fittings to hook up to the fuel rail. Pics of my fuel pump setup on my site below........let me know if you need anything else.

sweet setup thanx

I use a '95 Corvette in tank pump.
