What's a good way to route the front 1/4" lines for bags? I was wanting to plumb line from passenger side airbag, pass it through the crossmember to the drivers side. Then pass both lines through a small(factory)slot in cross member, then run lines down frame to the rear of truck...Problem is, when the lines go through slot in crossmember, they come about 3 inches from exhaust. Is that to close? Any plumbing suggestions, pics? Thanks.

I assume you plan on running DOT plastic line. If so, then yes that is too close to the exhaust.

My first choice would be to route the line in a different manner. An option would be to use section of fuel line to protect the airline.

Make sure you use grommets any place that the airline goes through metal.

I always put my DOT airline inside rubber hose in exposed areas. For my 1/2 lines I used 5/8 hose.

I went up thru the crossmember underneath the motor mount stand. (with rubber grommets)
Then down the inside of the frame rail using wire ties about every foot.

I just knew more drilling would be involved. I'm running out of drills.lol

If your budget allows, you could also get the insulation sleeves sold in speed shops and in Summit. I used them on brake lines and speedo cables, 3' lengths. They come in various diameters.

Sorry for the poor picture quality. Mine run out of the spring tower, through a plastic grommet, the right side runs along the front cross member (back side) to the left frame rail. The left side runs out of the tower to the frame rail into a "T" which is connected to the right side line and of course the feed line. I used line clamps every foot or so and also made use of tie wraps. The line is not as close to the shock as the picture would have you believe.

I carry 3' of line along with 2 couplers, push to connect, as my emergency airline repair kit. The kit also contains a tubing cutter from Harbor Freight. Hey, you never know.

Thanks for all the replies...I think that between the spark plug heat sleeve, and the fuel hose, I got it figured out. I'll put airlines in hose, put hose in sleeve...I think that with that setup, I'll be able to wrap this stuff around the exhaust, and not have an airline melt down.

Thanks again.
