I recently won an auction for a flu419 and it was delivered a few weeks ago. After changing the batteries and fuel lines I have it up and running.
The issue I was having is the air pressure regulator kept blowing off before it built any pressure in the tanks. The line from the regulator to the tank was very rotted and plugged. I used a Parker hydraulic fitting 6-10LXHU86-S this will convert the metric compression fitting into a -6 JIC fitting.
I also replaced the air pressure regulator I converted it from a Bosch to a wabco regulator.

This regulator has all the same dimensions and operates the same as the Bosch unit but cost $84.
