What controls the fueling on a stock RA since there is no fpr and no return line?

 

the pump braket has a built in regulator...

 

As PR_Mivec said, the fpr is built into the pump/bracket assembly that sits in your gas tank.

They made it that way just so they could make it a returnless system, to cut down on the evaporative emissions that results from the fuel being heated as it gets pumped up to the rail, only to be returned to the tank.

Makes it a bit more of a PITA for anyone who wants to play with their fuel pressure, though.

 

So If You Wanted To Put A Fpr In How Would You Go About Doing That?

 

there a thread already about that...
basically yuo will need an evo 8 fuel rail, stock or aftermarket and a regulator, run the retun line to the tank and there you go...

 

Do a search in these forums (the ralliart forced induction tech) and youll find one called "Fuel Cut" i think. That's the one that covers your question in quite nice detail.
