Typhoon Intake issues

Typhoon Intake issues Today I decided to install my typhoon intake I bought a while ago. To start with , I broke the oil pressure sensor but I replaced it.
Once I got the LS1 manifold off, I swapped over the map sensor and TB. I used tephlon paste thread sealer on all the fitting. Set the manifold on and tighten it down. Finally I hooked up all the fuel lines and prime the fuel system. Sure enough, gas starts spraying out of like 4 diffenent places. The crossover line leaked the worst. Just about evey fiting was leaking. The only thing that didnt leak was the injectors. I took the fuel rail apart and sorta made a new cross over from some extra parts in the kit. Put the fuel rails back on and primed the fuel. For a moment it didnt leak so I fired the car up. It idled good with no vacuum leaks, but minutes later the fuel rail started leaking again
What can I do to stop these leak?

make sure all the lines/fittings fit snugly and everything is hooked up properly. Intakes and many many other items do not come tightened and "ready to go" when you purchase them. You always gotta keep that in mind just in case cuz things like this will be sure to happen every once in a while. Now you gotta go back from the beginning and touch up everything you didnt double and triple check. Post up to see if you find the fix...I's say those fittings should be good but if anything use teflon on the fittings and/or some kind of sealant paste but teflon should do the job if you know what you are doing...

I used paste on the threaded fittings and nothing on
the -AN flares. I did mine using all my own fittings
and hose (Russell and Jeg's bits). Several of the -AN
were weepers, you have to retighten them after you
pressurize the system and leak-check. But the
threaded fittings, you are hoping are tight to start.
Though the kit warns you not to overtighten those
as the aluminum rail could split.
No leaks or even aroma, after the first snug-up.

I am putting one on in a couple weeks. I keep reading about this intake and it seems like a lot of people jump up and say they sell junk, but these same people most times havent even actually tried one. I havent found anyone that once they fixed the minor issues, didnt like the intake.
Keep us posted.

The only reason tape on AN fittings may help is if the sealing surface of the fitting is damaged. AN fittings are made with a 37° flare at the nose, and that is where they seal. The AN fittings have straight threads, unlike pipe threads which are tapered for their seal.
Before you reassemble your fuel system, take a close look at each fitting and each tapped hole. Also make sure the thread engagement is snug. Extra teflon tape can help if the threads are sloppy. If a pipe thread is tapped too deep, it will loose the taper it needs for a good seal.

I really do not understand why these people always jump on this company..... I have the same intake and it has never once been a problem. This intake sealed perfect, does not leak and help 17psi of boost through my procharger kit. Not everything is just a slap on and go. You have to make sure that the gaskets are on the right side cause it doe matter. I have never had a fitting leak....

Finally had time today to work on the car. Me and my buddy put the new fuel rails & crossover that PP sent. I guess my origanal rails were just machined wrong or something cuz the new rails and crossover sealed the first time. We used teflon tape instead of paste on the pipe fittings and left the AN fitting bare and it seems to have worked great. Im happy the car is back on the road. Now its time for a dyno tune. Thanks for the tips guys!

We installed mine on Sunday. It worked perfect, and actually smoothed out my idle a bit over the WS6. It looks awesome too. Gotta finish the nitrous rewire, and then maybe some dyno time. We put in a bigger cam, so I am expecting some bigger numbers.
