winstonusmc Posted November 25, 2013 Share Posted November 25, 2013 (edited) OK, yes I know that Pallnet makes an affordable rail, but I can't use it. I did buy one for the 11mm o-ring injectors and I found out my RB26 444cc injectors are 10.5mm. Guess I should have done research. I have already studied the construction of both the factory RB rail and the Pallnet rail. Two questions. First, why are the holes drilled off center? Is it to make the fuel flow smoother through the round bore of the rail? The factory rail is center. Second, is it totally necessary to step the injector bore in the rail? The stock rail is smooth on the injector bore and it doesn't even seem the o-ring goes up far enough to matter anyway. I am about to order a raw extrude rail from Ross. Not saying anything bad about available rails, as I was going to go with the Pallnet rail. This gives me the opportunity to have some fun with more fabricating. For those about to post it, yes I have searched. If there are topics on this, please post the link.

randy 77zt Posted November 25, 2013 Share Posted November 25, 2013 http://www.kinsler.com/page--Home-Page--13.html I built my own fuel rail with extruded rail from these guys. Quote Link to comment Share on other sites More sharing options...
winstonusmc Posted November 26, 2013 Author Share Posted November 26, 2013 I figure since I have to fab up rail mounts on my intake due to an over zealous shaving, no mounts, I would just fab one to begin with. Its going to be much cheaper than buying a set of injectors. Quote Link to comment Share on other sites More sharing options...

winstonusmc Posted December 12, 2013 Author Share Posted December 12, 2013 I figure out why the injector holes are drill off-center. It gives more room for the injector plugs. My plugs fit good even though the holes are in the center. Quote Link to comment Share on other sites More sharing options...
