Does anyone have a writeup on how to replace the fuel pressure regulator? I know i have to take off the whole manifold but is there anything special to do?

 

Na? Tii? S4? S5?

 

it's an na s4 sorry

 

FPR is located on the secondary fuel rail held on with two 10MM bolts. It comes right off. Probably don't need to remove the intake, just the rail.

 

Replacing with an aftermarket one?

 

no just doing a stock replacement, however with the position of it, i think i need to take of the whole manifold ><

 

sholdnt have to. if you have good tools and crafty hands you can do it. ive done it on my S4 T2.

supposedly the stock FPR is good for around 400 flywheel HP. dont know if id trust it that high, but if your HP goals are no where near that, youll be fine for sure.

 

Just pull the fuel rail.
