It worked great for 2 times I got one on my 69 camaro and I put one on my 99 when I swapped to a ls6 intake.The camaro fuel rail was returnless and my truck had a return.I simply plugged this sucker on the end of my fuel lines(engine bay) and made a short hose out of it to my fuel rail.I'm also running a walbro 255 lph in both vehicles.

did it seem like you were putting any extra pressure on the filter regulator? The complaint was that the part would break if there was any load from the fuel lines???

I used my stock fuel rails on a TBSS LS2 manifold....had to make my own mounts for them but all in all it worked out pretty well. One thing I would explore in your situation is possibly using the truck rails with a Vette/Fbody crossover tube...not sure if it would fit though. Just an idea. Also might check out some of the aftermarket fuel rails with the steel braided crossover and external boost referenced regulator. Those would be pretty pricey though.

I have L92 truck rails, that fit the L92 truck intake. The problem is not the rails just hooking them up on a 2003 that has two lines up to the fuel rail, and I dont want to hack anything in there. I have looked at my extra set of return rails with the reg and it wont work.

thanks again. after I got the right name for what I was looking for I found this
with the part numbers and pics
I even found some limited discussion about putting it in the engine bay, close to the fuel rails. With trucks I can see it being easier b/c of the extra room under the hood. When I find pieces to this L92 puzzle I am putting together I get excited that I might actually make it work...now getting the cam might be another story

If your stock rails with the return port on them won't fit, then I think you're gonna be stuck with a set of aftermarket rails and an external regulator if you want it to have it boost/vacuum referenced. That intake manifold looks almost identical to mine. Let me dig up some pics of what I did...maybe it will work for you.

I ground the stock mounting tabs off the stock rails, and created my own with strips of aluminum from the hardware store. The crossover tube barely clears. Yours may be different....looks like your injectors are not tilted as much and some of the mounting points are different, but it's worth a shot.
