i know,im talking about adding a hp cutout as added protection.i have my accumulator and hoses off right now,i looked at the lp switch last night and was supprised to see the adjustment screw.don,t see that in my field unless its a bulky metal box with cap tube in various lenths ending with a 1/4" flare nut and a 1/2" conduit knock-out. our encapsilated switches come in various cut in/out settings some with 24"leads and some without but none i,ve seen with that adjustment screw,thats just plain cool.now that i know i,ll bench test mine w/dry nitrogen before i put it in.when i add the high pressure safety i will have the manual reset variety so i have to check it if it ever toggles.im in no hurry to get the air going,not my dd.need to make it more road worthy first.24 psi seems a little low but ok.
