Air Pressure Will Not Stablize

Good Morning Everyone,

I am working with an Agilent G1600 AX capillary electrophoresis instrument. Recently I have been having issues getting the instrument to hold pressure. Per another forum post, I ordered Viton from an online source and fashioned new gaskets for the air pump. The gaskets were torn, so I thought that would solve my issue. However, the instrument cannot hold steady pressure. It starts around 250 mbar, shoots up to 890 mbar, then steadily declines until the software cancels the run. The system appears to pressurize and I have good suction at the point of the air filter, so I am unsure of what the problem could be. I have not been able to run my instrument for three days at this point and would appreciate any help I can get to get my research back up and running.
