Has anyone ever had a fuel rail nut walk out on them? I have been having a bogging problem at WOT since the install and can't figure out what it was, so I thought I would grab the good ol toolbox and double check to make sure everything was tight, I noticed a small little puddle of fuel on the intake manifold runner, and i looked back there and the driver side has walked out and the nut was gone. The passengerside and middle one were still tight but the driverside was popped up. Is there some sort of torque spec for the fuel rail or is it just one of those "as tight as you can get it" type of things. I have never had a problem with the fuel rail til I installed the 440cc injectors.

Any feedback would be nice.

 

a guy in my club has a turbo prelude and he had his kit along with aem fuel rail/fuel press. reg. and rc engineering injectors. the shop installed all this while he was in iraq and his wife picked the car up for him several months before he got back...any way a long story short after about a month of breaking it in we were going at it on this back road and he called me on the radio saying he could smell fuel, two of his injectors unseated completely loseing the o rings and soaking the engine with gas. turns out they didnt even install all the nuts...it only had two on it and the retaining clips were installed on the studs incorrectly.

 

I had a bolt back out on me. Drivers side.
