i have a fuel leakproblem in my 06. I recently purchased a speacer similar to the AAM one for nitrous or adding a fuel pressure gauge. Long story short i broke one of the heads of one of the bolts when ratcheting it down. I had to take the bracket it off to get the bolt out. When taking the bolt off i was wrestling with the bracket to get the broken bolt out. When i installed it back in with the spacer, it started leaking real bad right at the regulator spot. I took the regulator out and found that the O ring was slightly damaged. I replaced both O rings ( one on the regulator and the other on the backside of the braket that goes to the rear of the engine). I oiled the O rings this time and ratcheted everything down nice. I started the car up again and i am still leaking fuel but not as much as before. There is high pitched "whistling" type noise coming from the engint so i know it must be a small leak but definatley leaking. I dont think there is anything else to try so i was wondering if they made any type of gasket maker kinda like the RTV silicone stuff only made for fuel or to withstand fuel? Just trying to save myself $90 for that whole bracket assembly.

 

i also tried not using the spacer and just the stock regulator along and it still had that small leak.

 

If there are no burrs and the bolts are doing their job, AND u are using the proper O-Rings (O-Rings DO come in SAE and Metric)then it has to seal.

There is simply no sealant that will do the job in that case. NONE----Sorry
