Large pancake tanks? flat tanks..

Hey all,
So I want more air (among other things in life), and I’m thinking that a pancake tank would be perfect for under the trunk. The 4 gallon airlift pancake tank on hornblasters is too small for the price I think. Do you know of any 10-15 gallon pancake tanks or something similar?

Probably not possible, searched everywhere. The biggest pancake tank I could find was 6 gallons, and that was with a 120 volt compressor bolted to the top

6 gallon is biggest ive seen… How about getting 2 and connecting?

Well, that would only be 8 gallons and $200 or so for 2 airlift tanks. I’d imagine two 6 gallon tanks with compressors would be even more spendy.

At that point, it might be more worthwhile to get a Firestone 9277 19 gallon tank for ~$150 shipped, and stuff it in my trunk and run a line back to the front of my car. Not sure though, I’d rather keep tanks outside my car. We’ll see
