You need more than 3 gallons of reserve air. get at least another 3 gal tank. you can upgrade your fittings and line too, it wouldn't hurt you. i could hop the front of mine like 8" with 145 psi and airlift bags, 1/2"line and 10mm smc valves.
it can help you not hurt you to mount the valves as close to the bags as possible.
