I have some RC injectors on my b series. Using the stock fuel rail spacers, it seems like there is space on the top and bottom of the injectors. I snapped a couple of pics with my phone to show how they look installed. Should I leave them the way they are, or lose the spacers and crank down the fuel rail a liittle more?

 

could i mill those spacers and put them on top?

 

if the injectors leak you could put them on top so that the rail pushes injectors in farther.. if they dont leak then you should be ok.. as long as they are sealed your fine.

 

bro a word of advice RUN those spacer, they give them to you for a reason man. torque them down properly! if you decide not to run them and god forbid over torque your fuel rail on to your injector you run the possibility of damaging the electrical part of the injector where the clip attaches. just my two cents

 

yeah.. and if they werent sealing as if they werent in far enough he would have to make some adjustments. and have them pushed down a lil further.. i know they are there for a reason... but not all rails/ injectors /manifolds are designed the same so .. there are some that dont need spacers.. doesnt mean there going to squish the injectors to a pulp if not there.... just have to know what your doing.... just my opinion to.

 

i am probably going to shave down one side of the spacers on my bench grinder (so they fit on top) and put them on top of the fuel rail. as far as over torquing the fuel rail, thats not gonna happen. i know my strength, and i'm using a 1/4 drive ratchet to tighten everything down. clearly the injectors are not going down far enough, but by moving the spacers up to the top, it should put me in the money zone and give me some peace of mind. it won't look too good but hey

 

Try using some washers and save some time shaving them(you might need those later on), and to determine the clearance you have, you could add or minus the washers you put on.
