I’ve looked at instructions on a right way air suspension gauge installation and it looks straightforward. My question is instead of using one airbag for the source possibility of using 4 airbags.
here is what I am thinking. Install T fittings on all airbags, connect the main lines coming in to the T fittings, then connect the other outlets to a 4 way fitting and run the 1/4 hose to the gauge.
This way all 4 airbags are equalized under pressure and I’m thinking this would give a better reading.
Any thoughts if this is a better way? Or just stick to the instructions.

It's unnecessary. The pressure will be the same because they're all connected to together. Here's the science from Wikipedia:
Pascal's principle is defined as
A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
Pressure exerted on a fluid in an enclosed container is transmitted equally and undiminished to all parts of the container and acts at right angle to the enclosing walls.
Alternate definition: The pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.Bean Jr., LoneRanger, Goodysnap and 1 other person Thank this. -
The instructions will also say to check on flat level ground so each bag is extended the same amount.
LoneRanger Thanks this. -
No need, why have all those extra connections, with each one a ‘risk’? Within a few seconds all the air bags are equal anyway.
Bean Jr. and LoneRanger Thank this. -
I’m not familiar with air suspensions and I learn as I go. I was thinking the same but since I don’t know how the valves operate or if each airbag is isolated in the system or not, that is why I was thinking about equalizing the system.
I appreciate the feedback and information.blairandgretchen, Bean Jr. and Ross_Tech Thank this. -
