95 silverado bagged fittings, line and valve questions......

Ok got a truck with i think 8 valves 4 fill 4 dump, corect me if I'm wrong. My question is it has 3/8 treads on the valves and 3/8 lines and fittings. I'm wanting to replumb it to 1/2 but keep the valves. Will it hurt them running everything at 1/2"? I'm just wanting the air to fill the bags quicker and valves are expensive. Also my other question is there are 2 checkvalves on 2 of the 4 fill valves from the tank not sure if i need them or should i remove? And y only 2 not all 4?Any help appreciated.

yes you can run as large of line as you want as long as it reduces for your valves. leave the check valves. they are for safety. if you blow a line or bag it keeps you from losing all pressure in your tank. valves need that backpressure on the valves to stay closed. drain your tank and all bags will deflate.

So do i need 4 checkvalves? I just don't know y there are only 2.
