I installed my RBC intake manifold. I primed the fuel pump a couple of time. I started my car and there is fuel coming from the fuel rail and injector area. The car would climb in RPM 2k 2.5k 3k and higher. At first I thought it was my throttle cable but that wasnt it. When I turn the car off I hear a wierd hissing noise from the injectors. Please help.

Sounds like you have a ripped "O" ring on a injector, this is causing a vacuum leak condition as well as a fuel leak.


I always put a little fresh motor oil in a oil bottles cap and dip the injector ends into the oil to lubricate the "O"rings before installing them and the rail.

make sure you use the right spacing under the rail where it bolts up to the manifold . If it is not right the injector will not sit right and leak .

The problem may be in your fuel rail. BDL fuel rails have been known to not sit correctly when tightening that 12mm bolt. You have to drill out the hole just a tad bit to make that fuel rail sit correctly.

Also, I always put a thin layer of oil on the rubber when seating the seals. It makes the injector installation much easier.

The leak is causing it to surge. Check to see if the o-rings on the injectors are ok.
