Ok... will plain admit up front... should have done more research before pulling the trigger on this one, but it's on the truck, and already with the injector line "leak" problem. Waiting to hear from Banks, about a replacement line... but... will buying the line from Shield Deisel be a better solution?? The Banks line is steel, the one from Shield is Stainless Steel. I wasn't thrilled with the clearance between the line and the air horn on install... so I can't say I'm surprised it failed. So... what have others found?? Right now, I'm going to put the stock horn back on, with the original line, got to have the truck running.
