Here’s a small business with basically the same compressor.

Also available as a Trick Flate from TD-DISTRIBUTING a small business. They provide more kit options if you want and you support a small business. They're about the same price and cheaper than most other options.

I'm running 2 of these pumps on my onboard air system. Still can't beat the price of the compressors. I used 2 to help split the workload as well as increase the air up time even more! Also have a 40 gallon propane tank converted to air tank connecting both compressors. I'm running a 115 to 145 psi pressure switch and 150psi check valve. I have ran just about every air tool on the market now over the past 5 years. The system still works flawlessly and outperforms everyone's systems I've come across yet. Even the famous dual pump ARB kits that run close to $1000 or more. All together I have maybe $300 to $350 into my system. That's including fittings, check valves and pressure switch!

INSTRUCTIONS LIED, no presser switch to turn motor off. But that aside, used compresser for first time today and loved it. Aired up two tractor tires and was amazed with how fast it was. Your mods were spot on and basic. It needs a presser switch and some kind of air delivery that is quick and you can monitor the presser. I also noticed the power cable were a little warm. You covered at all. I think if you mounted a small tank somewhere you could run an impact. Great video!

This pump was tough to get. Thanks for the video on this!

Simple approach that should work well.
One improvement would be a large fuse or breaker on the battery end of the power leads.
There is a lot of opportunity for that coiled up jumper cable to rub and short on something while driving.
Alternatively, another "anderson style" quick connect close to the battery.

Holy hell, napa has them back in stock after over a year of being out of stock.

Nice work, for future work I suggest using grease on your drill bit and tap, that will hold on to the majority of the shavings.

The motor, not supposed to start under head pressure thing, is real.... Though I built something like this years ago, and I used an "unloader" type replacement air compressor switch, same as the one from my Craftsman 6 HP comp in my shop. They cost like $35.00 bucks, and the contacts, are 220 vac 20 amp rated. Which will hand your rapid 12 vac, high amp rapid start stop cycling you'll see hear, when not using a reservoir tank. Which can be a future upgrade, my friend 😜!!!! And fusing the power, at the battery, is a "must" for fire safety as mentioned by others here .. Accidentally burning your truck to the ground, would be more than a bummer 😕...Keep at it brother !!!

The factory unit has a pressure relief switch built into the inline gauge which you deleted, I'm not sure if I just missed it, but where did you put it on yours as it's a very important safety item required by UL and NFPA? Thanks

That 1/8-27 tap is a tapered pipe tap for 1/8" pipe, you don't run the tap all the way in, it's tapered and rule of thumb is you run tap in until you can turn fitting by hand 3 turns before needing a wrench to tighten

[larryjanson]

what about air tanks? it helps out a lot having your pump set up to fill a 3-5 gallon supply tank.

They all require modification to some degree. Even the arb (which though they come with a kit to do it). This particular compressor is about 2x faster at airing up than the Arb that cost 5x more.

[jeffig]

interesting since the owners manual on my new NAPA compress says it has a built-in pressure switch which will shut off the compressor when the trigger on the inflator is released. The compressor will restart once the trigger is depressed again. -- I guess it pays to "read the manual" :) I'll have to get a hose with a trigger on it and try.

[lifeISrecord]

Why did you go this route versus just buying one off the shelf meant for this purpose?

[Steve-yupq]

I wonder where you could mount it in the engine bay…. Is there even space for it in your truck?

[patpower]

This is on my list now! Where did you get the pressure switch? Whats the specs and model number? Thanks

[markkomorowski]

You tapped your pressure switch into the thermal cutoff power connection, everyone else is cutting the wire to the power switch and splicing the pressure switch into that.

I like your way better. Did it work for final setup, or did you have to move it?

[theschultz-ster]

I have the same one. Doing this tomorrow

[xflowerranch]

I’m confused. Why would you need so much cable lead if you have the long air lines? Isn’t it one or the other that’s needed? That’s a lot of cable just hanging around in your engine compartment

[salcigar]

Would you include a parts list particularly the TAP you used.
