fuel system

[tk66k]

i am building a 383 wanting to spray no more than 200 shot what fuel pump or pumps will i need ?

[LS2Tuner]

I would install a Walbro 255 pump and once you hit around 170 and up you might need to add a accumulator to aid in that initial hit so pressure doesn't have a spike drop. If you do the rail upgrade usually I find that added volume to help that initial drop.

you could upgrade the intank pump like LS2tuner says but run a standalone system along with that just for the nitrous. it has its own Pump and regulater....it can be run on high or low pressure. you dont need to worry about the added stress on the intank pump.

here's the link if your interested...we have 2 styles.:
