You could probably keep the tank and mount the solenoid where the water traps are. You've got plenty of room for a tee on the front side of that compressor, too.

Where's the relays? Is that being mounted under the truck? Why two lines going into each solenoid?


Leaning towards downsizing to a 0.5 gal tank: https://www.ebay.com/itm/0-5-Gallon...588096?hash=item19e06045c0:g:ZNYAAOSwYNxabLKl

Where I have the tank mounted is perfect as I have easy access to the drain plug, but I need to figure out how to mount the compressors above the tank. I think I can use two L-brackets and bolt it to the window cage, but it might rattle like all hell...

I'll get a 4-way female cross adapter, stick that on top the tank, and it'll have: 150 psi relief valve, 145 psi pressure switch, and a 80 psi barrel regulator going to a Tee, tee has 80 psi relief valve, then outlet on tee goes to solenoids.

the only relay will be on your pump.
those are switches not solenoids they mount beside your seat one line is pressure and the other is exhaust the 2 on the front go to the locker doesn't get any simpler or efficient way faster than an electric switch and way less to fail
and if you use a power tank instead of air it is already dry

I ran pneumatic switches too. No solenoid to fail. Requires a bit more airline plumbing and you are very limited in switch styles and their size makes them difficult to find a good spot, but you can if you're creative.
The switch to the left in the picture is a 3 way toggle. UP was to activate in cab winch controls. Middle was Off. DOWN was for power to the compressor/pressure switch.

I've hardly ever seen a solenoid fail. It almost never happens. I would not be scared to use them.

Fuck that cheap shit blue air line, though. Get the ARB heavy duty air lines.

You can fit the pump and solenoids in the rear cargo compartment behind a finisher. Still easy to get to assuming you're not all packed up if needed. But you get the pump and solenoids out of the weather and dust.

The pump will also fit under the hood if that's your flavor.

I ended up mounting a RRC air tank for a reserve.

I'm going with relays and solenoids. I have that D1 3-switch dash panel ready to go that I want to use for the lockers and compressor. I see the potential benefit of pneumatic switches, but I could also just carry a spare relay (which I already do) and a solenoid in the unlikely event of either failing while being protected inside the cab. I'll put a water trap on the frame rail to suck up any moisture or diff oil

way too much stuff to go wrong, no portability for air, pressure is wet, HD lines is a 90s thing and not repairable

Way too much to fail? Like what? The solenoid? Sure, it can fail. So can your starter solenoid. Does it happen regularly? If the pump fails just pressurize the reserve tank. It's not rocket science.

The portable air thing is not a concern. Why do you even need portable air? To fill your tires? You can do that with the ARB pump. I plumbed in two disconnects to fill tires.

The ARB pumps are not the fastest. ARB is not the only pump marker on the market. You have plenty of options for endless air.

And wet air? LOL.

I ran the "HD" ARB lines for well over 10 years and never touched them. They never broke, split or cracked. If they ever did start to leak you can just wrap some electrical tape around the hole and keep going. Not a big deal. Having a line that's less prone to abrasion is cheap insurance. Plumbing in all that blue line under carpet, behind the dash, and through the floorboards to pneumatic switches is a lot of failure points. I really don't understand how that's less prone to failure than a system that's been working well for decades. And shit, if you were that worried about failures why are you even running selectable lockers anyway? Just install a detroit and call it a day.

My Dad ran a carburetor for decades too

I've never had a cheap plastic line fail due to abrasion cut them a couple of times on rocks stuck in a joiner back on the trail

Lol Not even close to the line you have to run with a pump, everything is in the open if something did fail and no gear clamps or rubber hose, pumps, not any electrical connections and yes a Detroit is a failsafe

Both systems work fine and each has their pros/cons. There are no more connection points with pneumatic switches than there are with solenoids. You just have a little more airline running through the cab, no big deal.

How do you figure that? With pneumatic switches you're running a supply line, a charge line, and an exhaust line. If your supply line or charge line break your lockers no-worky. With solenoids you have a charge line only.

Not to mention there is no great way to mount the large pneumatic switches, as shown.

Exactly both doing what was currently relative

Sorry to be the one to tell you this, but Power Tanks are as current as a dash mounted Garmin GPS unit.

I suppose if you have your solenoids tapped right into your tank with a nipple then you eliminate those two airlines. But I have to tell you the airlines running inside my truck are the least of my worries.
i won't sit here and say your way sucks or my way is the best, though. Both work. Would I run pneumatic switches again, IDK.
