Alright - I've searched ith no luck so here go's -

Can the stock 6.0l truck fuel regulator that is located on the fuel rail handle boost? Or do I need to get one that will adjust with boost? Thanks.

 

The stock one on my truck works just fine. I have run it up to 12 psi boost pressure and see 68 psi or better fuel line pressure. I run a Walbro 255 lph inline pump and the stock in-tank pump and fuel lines.

 

Stock regulator here also, but on Magnuson fuel rails with 42# injectors. No problems at 11 psi.

 

from what I understand its actually a good thing the way the trucks are set up...as you go into boost the fuel pressure goes up or something like that...Kyle from KBRacing told me how it all works but its slipped my mind...Im sure one of the FI guys will enlighten us

 

Thanks - I didn't want to have to redo my fuel rails!

 

it is 1:1
for every # of boost it sees you should see a # increase in fp
