AIR TANK, 12gal or 8gal

[04 orange]

Is a 12 gal tank to big to run for my system. For my air ride system, I have contitech 2500 bags in the front and 2600 bags in the rear. I'll be using a air-zenith compressor. I have 6 blitzluft valves, for side to side in the front and just up and down for the rear. I'll be using 1/2in soft line, and I have a 175psi switch. I do have a 8gal tank, but I picked up this 12gal tank that is made for an 18 wheeler up cheap, and it fits perfect in the rear frame rails. Do yall think that the 12gal tank is going to be to much for this system.
