5excellent
By M. Pagano
installation was pretty simple and straight forward. just drill holes, put in screws and attach bolts. then just connect up wires and hoses and off you go. had no troubles with leaks and it runs fine. mounted the compressor in the lock box of my pickup truck, along with the air horn and valve.although, i modified the system a bit. besides adding a toggle switch to the compressor to shut it off, i also bought a few T-joints from the local hardware store and added:-a pressure gauge so i could see what the pressure is at. had to get extra hose for this so i could put the gauge in the cab of my pickup truck.-a safety relief valve that will automatically release pressure once it hits 125PSI. the pump should shut off at 110PSI though so this is only in case it doesn't shut off, or in case the air temp changes enough to drastically increase the pressure in the tank. its also useful to drain the tank if needed-a quick connect valve to easily attach other tools, mainly a tire inflater (the compressor came with one, but its quite cheap and the hose isn't long enough), maybe some pneumatic tools to make changing tires easier.-additional hose attachment for a possible additional air horn

I purchased this with a semi horn on here, works fine no leaks or problems. I mounted the whole kit underneath of my s10 bed. its been a month with no problems. youll need to buy some extra wire, as the kit didnt come with nearly enough. I also like the compressor for the fact it vibrates dirt off the underbody lol.
