I appreciate both of your videos. The seriousness of the switch is not articulated as well as it should be (if you are converting to the standard gas station fittings). This unit comes with an odd ball air fitting set up so the unit will always free flow when running. The attached fitting obviously minimizes this compressors capability's. Also the included hose is so bad that when I touched it after it sat in the car for a month the vinyl was off gassing so bad that the hose became disgusting. It was nasty I mean it was so slimy and gooey to the touch, that I needed to immediately replace the hose and that prompted me to start the fitting and pressure modifications. Once you adapt and add the standard 1/4" gas station fitting and there is nothing hooked up AND flowing, the compressor can and probably will instantly have a catastrophic over pressure failure. Your way of doing the electronic hookup is by far more clean and professional. I am going to wire it your way and mount the pressure switch externally like in the other video. I don't know why the other video showed cutting the wire. I don't do Overlanding, but most of the other 12V inexpensive compressors are mostly a huge waste of $$$$. This one works super fast and wont burn out before the tires get filled. My only wish is that they go to a more efficient motor that does not draw 90 AMPS.
I picked up one of these pump last year and since installed the pressure switch like you did. I suggest you take the two pump head apart and clean it out really good. Quality control from China is lacking and I found a lot of metal shavings and casting debris in both my pump head.
Something worth considering to install is a Viair Check Valve between the coupler and manifold. It keeps the line pressure away from the compressor. Meaning the motor won't have to start up under 90-120psi every time. Less stress and fewer peak amps drawn.
@@PhoRunner been reading up on why this style compressor dies and people seem to associate it with the motor starting under load. Also the Viair website mentions how their check valves work in that sense.
Is doing pressure cut of switch mod still worth it when using a 4 hose kit? My compressor already has US standard 1/4” fitting but it doesn’t have a pressure shut off, I plan to use a 4 tire hose kit
I would always add one just for the safety aspect . If you get distracted or walk away while you are airing up the compressor would keep pumping until a tire or the hose blew.

Great video. Weekend project found

Thanks for the extra info on the hose!! Yeah not sure why folks cut it haha

True… I need to lube mine up. I know alot have reported one side being dry
@@PhoRunner there's a Facebook Group that is dedicated to these pump. Pretty good enough if you weed out the noise.
Awesome video man! I wish I had been able to get one of these compressors at Napa before they sold out
They’ll be back!!
@PhoRunner
They are back. Currently $157.
Very informative, thanks for sharing.

Smart

Awesome idea.
Thx
I think the new ones come with the pressure switch. I'm guessing i just need to replace the cheap rubber hose with a better quality one?
Awesome thanks for the info
No problem!
Good job on the video.
Thanks sir
Great Video and simple and great explanation and clear
Glad it was helpful!
Nice way to hide the switch another alternative if you don’t want to drill the existing 1/8 hole you could add a 1/8 npt to 1/4 npt adapter
Carnicero! Hahah I have the same compressor from napa in box. Imma do that mod. Thanks big dawg
Be extra careful with the tap :)
You do a very good job making these videos, thanks!
Thanks bud!
Awesome video!
Thx
Question, why a 1/4 tap but a 1/8 pressure switch?
The oem hole is 1/8” so the pressure switch will go there. The new hole for the new quick fitting is 1/4”.
Excellent! You won a new subscriber!
Welcome aboard!
Another great video
Will this work with the new black rebranded Napa compressor? Assuming they’re the same and everything will still fit
I’m a little late to the party on this, but just recently found out about this compressor. How has it held up?
So far so good
Is it hard to get them now
Yes it is
I tried to purchase one but always out of stock smh
Does it matter what the "on" pressure is? I understand the off should be relative to the compressor but does can the on be too high?
Id get a lower psi pressure switch. Doesn’t really matter really
Were you able to find a place to mount the compressor?
nope I haven't but the cargo area in the rear hatch seems like a spot that could work with some mods.
When you loosen the manifold to leave the pressure switch at the bottom did the manifold not leak?
It did not
Mine has a leak after doing it. Did u find a fix?
@@alh5470 I did it and mine didn’t leak I was just curious if it leaked before I did it.
Is doing pressure cut of switch mod still worth it when using a 4 hose kit? My compressor already has US standard 1/4” fitting but it doesn’t have a pressure shut off, I plan to use a 4 tire hose kit
It’s not really necessary tbh
I would always add one just for the safety aspect . If you get distracted or walk away while you are airing up the compressor would keep pumping until a tire or the hose blew.
The hose will likely go first
Why does the pressure switch need to go in the same line as the fitting??
That way the quick disconnect and manifold don’t explode like a mini pipe bomb.
@@PhoRunner It looks like it could fit better elsewhere on the manifold. Does it need to go right next to the fitting for accuracy or something?
@djrodriguez6582 I would do a different spot yes. It’s too close to existing hole and I wouldn’t do it like that again
@PhoRunner thanks for the insight 👍
@@PhoRunnerwhere would you put it?
We can send you a beast, dual cylinder air compressor, more powerful, are you interested in testing it?
Sure. Email me. Phorunner559@gmail.com
So not sure if you have any suggestions but my air pressure switch seems to not function. Bought two from Amazon and neither shut off the compressor
Does it have a leak?
@@PhoRunner its leaking around the head/rail attachment. looks like this is going to be a bigger project than I had hoped
:( yah with that leak, it can’t build pressure and the switch won’t work
19 inch wrench gaaadayum 🤣
that fitting going to be STEAMING HOT after use. no thanks
