My 2001 AmTran FE with outward-opening air door needs the regulator and dump valve replaced. Old reg didn't have a gauge, new one does (also has a dryer filter--yay I guess). Anybody able to tell me what I should set the pressure to? First time I've had to do this!!! Bird and Thomas don't use this setup.
AmTran's very helpful sticker on the access door just says "Air pressure has been adjusted to ensure safe operation". Gee thanks!
