Air compressor and tank mounting

[mfontana]

I want to purchase and install a 12 volt air compressor with a 1/2 or 1 gallon tank on my 2003 GMC, Extended Cab, 2500HD Duramax. The compressor will provide air for rear air bags and a air horn. I would prefer to use one dual needle air gauge. With the extreme quality and workmanship displayed in many of the member truck photo's, I would appreciate any suggestions regarding the products to use and the gauge/controls, mounting locations. Also suggestions regarding the location of the compressor and the tank. What about an air dryer to avoid moisture issues.

I put on a larger compressor than was recommended for the air bags and then I added a 2 gal. tank. They are both bolted to the floor board underneath the front passenger seat. I plan on taking out the 2 gal. tank and installing a larger one as the capacity is just too small.

I just installed a BD Exhaust brake which uses an air compressor to activate it. I have a tank off of a truck I plan on installing. The air pressure to the brake must be regulated, so that means I can't come right out of the tank until I can figure out how to do this, I'm sure there is a simple solution, but haven't had a chance to research it yet. From the tank I will also have a quick coupler so I can air tires or whatever. Once the tank is full the brake doesn't require a lot of air to activate, so the compressor shouldn't be running all of the time. tpitt

I'm doing the same set-up you've described, mfontana, and I popped for a Dakota Digital gauge. I had it re-programmed to read only left and right side pressure, plus tank pressure. I'm going to install the gauge (rectangular aluminum bezel, approx. 3" long by 2" high) plus the two electric switches, in the block-out plate in the front of my overhead console (where rear a/c control would normally be). Since I'm going to be using electric solenoids for air control, there will be no air lines into the cab. Sorry, don't have any pics yet, as I am still in the design and programming phase of making a billet aluminum panel for the console.

mfontana,

I would highly recommend adding an air dryer. A small Desiccant type dryer can be bought for around $75. With what you have invested in air springs etc, this will easily pay for itself in the life and performance of the air operated parts.

It might be worth looking at some of the micro filter/lubricator/regulators (FLR's)these run around $100 and provide an extra measure of protection. The number one service issue on big rigs is failure to supply clean, dry air to brakes and suspensions!

Thanks for the suggestions! What seems to be the best location, under the hood for the compressor or under the passenger side of a extended cab?

See my sig for a link to my airhorn install pictures. The tank may be a bit smaller than you are looking for though.

Blacktruck-1,
What brand air compressor did you mount? Do you have any specs on the unit. Thanks in advance for your help.

The compressor came with the Hadley air horns in a kit. If you need the specs I'll post them tomorrow--Just got home from work and Its a little dark outside--rainy too.
