[AT] Massey 65 LPG fuel line

 Propane hose is generally wire reinforced for pressure.  Never heard of the conductivity issue but it certainly makes some sense.Propane hose has a pricked cover to let gas escape and not get trapped if you have a leaky liner.  This is definitely a safety issue.

I installed many propane systems on pickups trucks and tractors back when propane was only 0.12/gal.  We used copper for the lines from the tank to the heat exchanger on all the trucks and tractors.  We also flared the copper lines they fittings were very similar to water line fittings but we used refrigeration grade copper.  I have used air line for both vapor and liquid propane many times and not had a problem.  In the old days i think the propane hoses had a wire under the cover that made sure there was conductivity between the tank and the heat exchanger.  The tank was bolted to the truck, and the heat exchanger was bolted to the body, so I don't think the wire in the hose was really needed.  The use a wired hose for a filler hose from the big tank to the fuel tank just to eliminate sparks from static...

  I was using my 65 with a box blade to level my yard when it stoped as in out of fuel. Began to refuel and noticed a leak in the hose from the line that  connects the vapor outlet from the tank to the filter. I repaired it by using a 3/8 air line hose and finished what I was doing. I don't know what propane will do to this line over time. Is there a standard to look for to replace this hose and where can I find it. BTW before I got this tractor someone had replaced the liquid line to the filter with copper tubing with a flare fitting, is this a good fix. 
  thanks Ray
