Fuel Rail Dilemma

I have interference with my fuel inlet and one of the coil packs - see pic. The manifold is an LS6 and the coil packs are fr a truck - obviously incompatible. My thought was to cut the inlet tube just before it makes the 90 deg turn under the fuel rail and use a Swagelok compression fitting and run the line straight out the back. I don't know what size the tube is (assume metric - haven't mic'd it yet) but I'm sure I can find a fitting that will work. Has anyone done something similar? Thanks. -Bob

I had the same issue and just left one bolt off of the coil pack to get the car running - I'll wait and see what you come up with!
But, I wonder if you could get a tubing bender in there and put a 45 on it?

Just cut it and braze a 90 in, while your at it, braze a AN -6 fitting on too... that way you can eliminate the quick disconnect for a more secure AN fitting.

I was wondering if the existing fittings were brazed, silver soldered, or ??

I took mine down to a tubing shop, he had bulk fittings and he brazed it on for me for $10 (parts and labor).

Why couldn't you just cut the support strap (the one with the single spot weld) and carefully bend the tube in the dirsction you need it to go?

You can try it, but most likely the tube will fold or twist at where you are trying to bend it. If you going to do something, it is better to do it right the 1st time.
