Question Increase volume of air pump without physical change

[Joe Hogan]

The air pump that actuates the lift door air cylinder is marginal. I'd like to find a way to increase the air volume without physically changing the pump or components. The Newmar tech swapped the motor/pump for new one. No change.

Any thoughts on this? Up maybe 10-20% should be enough....maybe.

Here is the pump.

My 17DS does not have an air lift door so I’m not familiar with it. However, maybe a small accumulator tank might work in this situation.
