I started to re-plumb the air lines on my Deuce. So far, the compressor to regulator is done, as it somehow developed a hole in it close to the firewall, on the side AWAY from the engine (I have NO idea how that could happen, when there is literally NOTHING for it to touch) and got the fittings and nylon line to do the air pressure gauge and the T-case switch under the dash. I also made sure to support the new compressor to regulator line with Adel clamps. The local Frieghtliner shop sells nylon line by the foot, unlike Fleetpride, who wants to sell me a whole (100 ft) roll, along with the needed fittings. Fuel lines will be after the air lines, of course, along with the spin-on filter conversions.
I also am adding this thing- Parker Model 500FG Diesel Fuel Filter/Water Separator- it has a 10 Micron filter in it, along with a "pop" out for emergency fuel bypass. I got it for $5 back at KAMO last year.
