I tried to keep it running on ether, but no love, the lift pump had me thinking as my dad had to replace it some 15 years ago when he acquired this compressor.
I have flow out of the pump...so rigged a fuel pressure gauge to the output of the pump, and have about 6/7 PSI.
Been searching, but can't find the pressure spec's for it.
I guess I should take it apart and see if the diaphragm ruptured when I had it running before.
PS, I did drain the tank the best I could, there was no crud floating in it and no rust that I could see with my flashlight.
