Starting to work on this project now that I finished up my rock sliders. I'll update my other thread with pics of that process soon.
I drained and removed my windshield wiper fluid reservoir, although I dropped one of the bolts that secured it between the compressor and the wheel well and can't get it out lol. First going to try to jump my compressor directly from my battery. If that works I have plenty of wiring and an aircraft switch that I can wire up the compressor to, so I can turn it on and off with the flip of a switch in the cab.
I pulled out all of the push to connect air lines from the rest of the truck, and I'll repurpose it to route it to a tank I'm buying. They sell air tanks for use with air horns and whatnot, and I can get a 3 gallon one that goes up to 300 psi with 2 ports for $50. There's only one air line coming out of the compressor, so I'll route that to a push to connect to 1/4 npt fitting into the tank, and then I'll route a regular 1/4 line out of the other port in the tank, and I'm planning on routing a pressure gauge back into the cab some where. Maybe put a pressure relief valve somewhere in the system, but the shop manual says the compressor has a pressure relief valve built into it, so that may be redundant. Ill also route a line to a quick release fitting that I'll install in the bumper. That way I'll have a port I can use to air up the tires with quick and easy access from the outside of the truck.
Was wondering if anyone sees an issue running the compressor right off the battery. The switch I'm using is rated to 15amps so if anything goes wrong that'll function as a fuse lol.
I'll post some pics later this week, not too much to see until I buy the tank and the fittings though. But everything hinges on being able to jump the compressor off the battery.
