I live near an employee and they hand delivered the replacement part that broke (see image). They said they hadn't seen the part break before. I didn't know about the pipe tape when they stopped by my apartment so I could let them know they should do a quality check. Super nice folks though!I ended up replacing that Japan standard hose fittings with an American standard fitting and hoses. Takes no time at all to air up (IT'S NOT A RACE!). I'd say it takes about 10 minutes from the time I stop, get the air compressor bag out, open the hood, take off the air caps and start airing back up is probably 10-15 minutes. Sometimes I do have to let parts cool down if it's 80 degrees or more outside before I toss the air compressor back in the bag.When I took the Smittybilt factory Japanese fitting off, I noticed pipe tape was covering the opening (see image).The factory gauge on this air compressor is a complete joke and worthless. If you use it, figure out where the pressure is by airing up and keep checking. Then track what the air pressure shows on the pump. Here are my air up notes:2020 4Runner TRD Off RoadSmittybilt 2781 gauge is worthless32 PSI on Smittybilt = 35 PSI on dash computer31 = 34 dash10 = 20 dashPump air ON Smittybilt compressor to read 42 1/2 PSI on gauge TO GET to ~34 PSI on DASH then take air out to get to PSI for ambient - This was never really consistent at all. I ended up abandoning this method.So what I do now (after I replaced the factory fitting, gauge, hoses and air nozzle)Hookup the Smittybilt power leads to the battery and close the hood while watching out for the power cables from getting smashed (you don't have to slam the hood, you just have to get the sensor to trigger the hood is closed).What's my tire pressure supposed to be at?My 4runner door jamb label says tires should be 32 PSI at rest ambient temperature. Meaning tires are not hot from driving on the road and whatever the ambient temperature is. At 10 degrees ambient temp tires are at 32 PSI. 120 degrees ambient temp tires are at 32 PSI. However, if you're at 32 PSI in 120 degrees and drive to where it's 10 degrees, your tire pressure will be 21 PSI when the tires reach ambient temperature when they cool off from the road friction.I close all doors with the drivers side window open all the way. Reach through the window and change the gauge cluster to show TPMS (cluster will switch back to something else if ANY door / hood is open) and air up to when it reads 31 PSI on the dash. By the time you get back to the air compressor and turn it off, it'll hit 32 PSI. 1 PSI is added from the time I see the dash change to when I get to the power switch on the air pump.TPMS rounds PSI up and down. 31.6 PSI is 32 PSI on the gauge cluster and 32.4 is 32 PSI on the dash. It's really not rocket science but if you can get within 2 PSI on all 4 tires, that's optimal.You can always add or remove air, but be mindful of the ambient air temperature and allow 1 PSI per 10 degrees of ambient air temperature. And whether you're going to drive to hotter or cooler places.Parts used to switch over from Japan standard to US Standard fittings (This Smittybilt is an open flow system):https://www.amazon.com/gp/product/B00EVRKSQE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B078Z98GF2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B07MCTC6NN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B089LV75HP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B07MCTC6NN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
