    Over-torqued bolts on fuel rail

    I was completing my winterization on my 2007 RXT and wanted to fog/lubricate the valves ,so removed the fuel rail as detailed in the BRP manual. When I was reinstalling ,I accidently misread the torque setting. 10NM or 89 in-lbs. I ended up using my Schwaben torque wrench which is for foot-pounds.......as I started to tighten I realized my mistake,but have definitely went past 8 foot-pounds. Would I be ok with just purchasing new fuel rail bolts and torqing them correctly or should I have the threads retapped?

    If they are tight it's Ok. If you have already spun the threads in the intake you'll have to back up and punt. Those bolts are basically just hand tight to hold the injectors tight against the intake and o'rings.

    torque fuel rail thats a new one for me they are fine just snugged up

    if you have spun the brass inserts, dont worry, there are a couple ways to fix it

    1. pull insert out using the bolt, heat gun the manifold and then insert the bushing back in then clamp the plastic around it tight w some pliers

    2. pull insert out using the bolt, epoxy the insert back in

    I even add a bit of anti seize to the threads, just to make sure they release next season.

    The service manual calls for blue loctite and 80in-lb. The issue was over-torquing not seized bolts. Fuel rail is one thing I would not experiment with.

    i would, its always in vacuum there so pulling the injectors inward, also the injectors have clips holding them to the fuel rail, good and tight is fine, 14yrs and counting no issues

    Yeah it's under vacuum if you ride like a granny Once you're into positive boost ...well self explanatory

    Anyway, by experimenting I was referring to not using loctite or even weirder using anti-seize on the bolts holding the rail. No issue with epoxy to reattach the brass if done properly.

    I have also heated the insert with a propane torch and just pressed it back in. Then let it cool down and good to go!
