on board air

ok, i wanted on board air, however i didnt want to pay a lot and i sure didnt want to give up my air conditioning either. so this is how i did it. a cadillac air ride pump from the pick a part, $15.00. a 1.5 gallon air tank that i was lucky enough to find mounted under an old truck, this cost $10. i mounted everything very clean and plumbed it all with compression fittings and copper tubing, now.... i need a high pressure cut out switch. i want one that kicks on at about 95 - 105 psi. where can i get one at for cheap??? i have allready tried a/c high pressure switches but they require much more than 100 psi, ive also looked into power steering switches but they too need much more also. the air ride shops are wanting around $40 - $50 for a switch. does anyone Know where or what i can get one from that will cycle around 100 psi? if so please let me know. oh yeah, just in case anyone was wondering if a caddy air ride pump could really work, yes it does. it takes a while but it will make 130 psi. it is more than enough to fill a tire or inflate a raft. what would you do with a huge $500 compressor anyways? work on cars on the side of the freeway? LOL.

I've installed on board air in my bronco II using the a/c pump...I used a pressure switch that cuts on at 90psi and off at 120psi. I'm also using a 30gallon tank mounted in the back of the broncoII.
I got my pressure switch off ebay for $15. This IS the kind of switch you will need. It will not hurt anything. My brother has OBA on his jeep and he only uses a small 2 gallon tank and uses the same switch. I use 30 gallon tank so i can have a big cushion tank for lots of air to run the impact gun at a better efficency rate.
So go with the 90/120 switch and you'll be fine. If you want to check things out further go to onboardair.com
All the switch does is controll how much air is pumped into your cushion tank before cutting on/off. It will not affect you blowing up a tire..u controll the amount of air you use by pressing the chuck on and taking it off..know what i mean?

Get a regulator off a air comprssor. That way youcontrol when it shuts off and the psi your useing.

A regulator would only be necessary when you need to have air at a certain pressure, like painting. It is completely unnecessary when you're filling tires - actually, it would probably mean less airflow because it adds restriction. Also, the regulator has nothing to do with whether or not the compressor is running - the pressure switch that Stuck was talking about does that.

well, i looked on ebay but didnt want to wait. so i went to a local 4 wheel drive shop and picked one up. it turns on at 85 psi and off at 105 psi. i figure that this will work fine. anything above 105 psi might work my caddy air ride pump a little too hard. LOL. i put it on and it works great, however the pump was only $15 and the tank only $10. both from the pick a part. the pressure switch was $40!!! oh well at least it all works. oh and for the regular compressor regulator, i dont want to have to monkey with anything. i just wanna be able to connect the hose to the quick coupler and go.

thanks.
