Air tank size

[1966ponyguy]

This may have been covered in past posts, I did look, but didn't find what I was after. I've order 4 2600's for our 68 swb. Have done 75 crossmember swap for front disc and swaped the rear to keep the 5 lugs all around. All bags will be mounted in stock coil locations. How much tank do I need. I have moved a S10 fuel tank between the frame rails, and have my crossmember cut and a pipe welded in to run the exhaust through it. Running out of room fast. I've seen everything from 2 1 gallon tanks to a 3 gallon tank used. Don't really want to mount tank in bed.

I had 10 gallons of air. 2- 5 gallon tanks with 4 ports on each one. Today I took out on of the 5 gallons tanks. So I now have only 5 gallons and it is fine.

I was think more in the line of 1 to 2 gallons. I know it's small, but it would tuck out of the way easy. I don't plan on hammering on the bags. I had planned on making a tank about 4" inside dia 3/16 wall and welding 2 hacked up compressed gas cylinder caps onto the ends. I would feel totally safe with my welding holding 125 to 140 psi. That would easily fit between the frame rails behind the fuel tank. Maybe a problem if you were rear ended. I did the conversion and came up with just over 1.5 gallons, but at 31" long, my math must be off. Still working on it

I really don't think you will have enough air to lift the truck from 0 psi to ride height. You would have to wait for your compressor to fill the tank back up before you can lift the front end. Once your tank reaches 85psi or so it will not be enough to lift your truck. I had a 2.5 gallon tank on my old c10. It was only for the rear bags, but it took forever. I add another 3 gallon tank to that system. Most companies will tell you 3 gallons for the front and 3 for the rear.

Methinks you didn't read the link I provided above. Lifts are going to take 5+ minutes minimum with that small quantity of air... as you'll be waiting on the compressor to cycle at LEAST once after you empty the tank. But it sounds like you've got a plan... so... enjoy.

I could get about 2 lifts out of my 5 gallon. I would say a 5 gallon would be standard (2 small tanks).

Thanks all, I did read the links and several more, but no one was really discussing tanks that small. I respect the comments from this board or I would not ask for them, I will be hunting for another place to put a 5+ gallon tank. Sounds like it would be do-able, just a pain the the butt and I already have plenty of those.

I went with a dual compressor and dual 5 gallon slim tank setup. Can't give you any real world feedback yet though because it not plumbed.
