My Pro Comp rails did the same thing. The rails are pipe thread and the supplied fittings are O ring. They will leak. Weld the fittings to the rails (be careful, the alloy is total ****) or get pipe fittings.
I'll bet Pro Comp and and CX Racing get their fuel rails from the same place, Cheng Shen Famous Good Luck Fuel Rail Concern.

I'm going to use thinner o-rings and pressurize it with shop air...that should be a godo enough test I would think. But yeah, what a hassle. They were 119.00 with the fitting and a liquid-filled pressure gauge so the price was attractive. Even if they need to be welded-up its still a good deal (provided they weld up right as mentioned prior).

Make sure you get some longer screws for the mounting brackets, I had the same rails for a bit, the screws in the back on the driver side pulled out and the rail lifted about a 1/8th of an inch, when that happened the O-ring on injector number 7 pushed out, I got lucky for the most part had just made a pass down the 1/8th and was on the return road when I smelled some gas, wasn't sure if it was my car and pulled up to the slip booth and the car went up in flames, lucky for me the booth had a extinguisher and we had it out quick enough it didnt hurt anything other than the plastic cowl. Had the car back out the next night.
Weld the fittings on, get some longer screws and locktite them, and they will work good for you. Good luck.

That's a total bummer, holy hell you're lucky it wasn't a lot worse! My Pro Comp rails came with hardware that was too long and the rails popped off a couple times before I figured it out. Lucky for me I was testing and had no hood on the car so I could see the fuel hit the windshield right away.
Another sign of cheap rails, mine came with a braided steel crossover line at the front that had -6 AN 90's on either end. Funny thing though, my -6 AN wrench didn't fit them. Fit all the XRP -6 fittings on the car though!

Thanks for the tips guys. I will need to make my own hold downs b/c the ones that came with the kit don't seem to work with the truck intake. I can only assume they were for a LS1/6 intake. Easy enough to do though with some metal angle.
