Yes.. it is IN! (does the little happy dance)
For a few hours there I was beating my head trying to figure out what to do and why this f... fine piece of hardware wouldn't fit.
So what to do.
A: take out the BFH
..ok..
Well, what do you know, it sorta fits. Just too tight by about 1/16".
As fate would have it, I have a perfect solution to that problem in the form of my angle grinder. (no, I didn't grind the header) :) I took a close look at the motor mount. Beefy sucker, about 1/4" thick and with a substantial cross section so it's not going to miss a little moon shaped section. ..grind.. ..grind.. test fit. (explicative) ..grind..
Finally! I left it about 3/32" clearance, hope that's enough to prevent noise. Shouldn't expand any that direction anyway and that part of the mount doesn't move.
Here's a clue. Unless you actually want to there isn't a reason to take the rail off. But if you do, fit the injectors to the rail first then press the whole thing into the header. Good ol spit makes a great o-ring lube. (ok, I see you laughing back there, that's not what I meant)
Will say one thing, it's hard getting to the bolts with the stock exhaust manifold, but it's a freeging bear to get at the bolts with the new one. Had to hand torque one bolt, couldn't even get a socket on it.
It's a Jeep thing, and I'm starting to understand.
