I'm currently running two 480c's and an 8 1/2 gallon tank. I'm working on my trunk this winter and I'm going with two 5 gallon tanks (one on each side) and 4 total 480c's. Do I have to run 200 PSI pressure switches on each tank if I connect them together? And what about gauges? Or is one of each on the whole system OK? And what if I run all 3 tanks and have them all ran together?
I plan on running hard lines in the trunk for looks.
One other question.... What is your opinion on upgrading my Alternator and adding a battery? Needed or not?
