I have bought and installed 3 kits from Siege...they are great people to deal with but even they will tell you to stay the hell away from the compressor/tank one piece set up. They are a POS...period. The check valves are notorious for leaking...the compressors dont pump enough volume to ever fill the tank up and they get HOOOT! I went through two trying to get one that worked for my friend and finally they told me themselves to get the other one because they have had nothing but trouble with the one piece units.

 

I used to like my Seige kit, but I should of got the 2 peice unit as well. Right now my kit is leaking somewhere so it's always kicking on to build up. Taking vacation next week so I should have it fixed soon.

 

Thanks for the advise fellas, sounds like the two piece is the way to go. Once again this site has probably costs me money in mods but in the long run saved me money and headaches with good advise.

Thanks again.

 

This is the way I mounted mine, Front of the gas tank under the drivers seat and didnt have to mod or remove anything. The tank and compesser are mounted under the passerger side of the outter frame rail which also didnt have to mod or remove.. Still have my fullsize spare and air flow to my trans/oil cooler under the front bumper... Why remove the spare or add a air tank to the front of our trucks when theres no need to? I have the omega 3 stack horns with the viair 380c and a normal tank so dont say it wont fit. The ext cab has more room by the gas tank then the screw does..
Dont mind the dirty undercab, I went alittle mudding over the weekend and it hasnt flooded to get a undercarriage wash.
