It is Part # 2
on the backside of the throttle body unit.
I think I used some 1/2" long nylon spacers from the hardware store and a couple of M5x25 length screws on mine. You need to remove the gas tank to get to it. Be careful not to drop the screws too many times as they can get lost!
Fwiw, I would not recommend
changing the female plastic (Delrin) quick-disconnect coupling on the gas tank (to a metal quick-disconnect) while in there either! I might
change the male end on the hose to the fuel injector's distribution line to a metal one, but that's about it. The risk of the $500 plastic fuel-pump mounting plate cracking is too great to gamble on (It's sealed with some goop known only to BMW AG, probably flared a bit from heat and age by now and have small stress cracks forming - the consequences may be that the pipe-thread will be looser for the new one and may bottom out meaning it will leak!
) <damhik either!
>. The male end one is the one that could conceivably go wrong and leak (O-ring and glued fitting), but if it ain't broke or leaking I'd leave it alone!
- unless you feel $500 is a gamble you'd like to make on a piece of plastic pipe thread that might
be damaged by you, or just stressed from age.
The Power FRK is a cool add though and you can tuck it up forward and under the brace near the back of the battery bracket or gas tank brace. Fit's tight there with a bit of double-sided sticky tape. Just make sure the wires clear the cam and screw when the throttle is cranked wide open.
