Sorry if this seems lame, but my TPI406 has the stock FPR and I have no clue where these adjustable FPR's go. Do they simply replace the stock one? How difficult to swap in the new one? How much $$ for an AFPR?

Thanks in advance.

Yes you simply replace the stock one (passenger side underneith the plenum towards the rear of the fuel rail). I made and recommend making your own, its super simple and beats blowing $50 on one that somebody else made. Just braze a low pro nut into the center of the cap, and put a quarter under the cap and a bolt into it (make sure its air tight because of vacum) and you're good to go.

Hi,

Your gonna need a T10 security bit. The stock cap bolts on the regulator have the little posts in them, like cable box's.


Whats the quarter for?? I welded a nut on the bottom of my bolt, so it would center better.
