Kyle,
I replaced mine with longer tubes. As I've pretty much submerged my
31" tires, the stock height just wasn't enough for me. The plastic
cap on the end is ventilated to allow air to flow through. Pull it
off and you'll see what I mean.
I ran the front tube up as high as I could get it and brought the
rear one along the frame rail to the engine compartment, like you're
thinking of doing. The only problem I had with the rear one was
trying to figure out what I could tie it to so that it doesn't hang
down.
When I bought the extra tube, I just yanked the front one off,
carried it in to the parts counter at Auto Zone, and told them "I
need 20 feet of this." I wanted some extra to play with. I re-used
the stock plastic caps.
The rubber tubing just fits over the 'nipple' connectors on the
axles. They don't have clamps or RTV stock, so I didn't even think
to use anything like that. I haven't had any problem. It's actually
kind of a bear to get off.
Any other questions, just ask.
