I was going to put my camper on my truck and thought I would add a little air to the airbags. The compressor wouldn't work, it blew the fuse. I took the pump off the truck, took it apart and found it all corroded, and stuck. It was like the stuff you find around battery terminals. It's a firestone pump and I couldn't believe how cheaply it is made. Instead of rings on the piston it has a leather (I think) seal. Anyway I cleaned it all up, coated everything with Vaseline and put it back together, works fine for now. Anyone ever have the same problem?
