bags losing pressure but not leaking

so i have a friend who just bagged a caprice he has 2 compressors going to 1 tank and then has a second tank thats teed into the first one. when he lifts the nose its fine but if he lifts the nose and then plays with the back up down up down the front starts to lose pressure i think he needs a check valve somewhere but where and help suggestions would be great

yes it needs check valves

He would probably need a check valve or two between the front bags and the tank depending on if theres one line or two to the front.

u are losing air pressure in your tank. and when the psi is lower in the tank then the front bags it will rob the air from the front bags
