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.
