Test, Yeah, I understand about not running a live line in the cab, but i did it i my 04. 5. Talked it over w/a couple fellers, insulated the tubing, it has the brass ferrules to secure it, worked well for over a year and a half. Kind of wondering if this is good or bad( in cab lines),also wondering about necessity vs a pyro for example.
Redfuel, No danin doesn't make an O. P. gauge, don't know how come there isn't enough demand for them.
