I'd get rid of that and go one line to the pump.

It sounds like you have an air leak somewhere along your lines. try to see if you lines alone will hold a vacuum. Disconnect them at the rear sump (obviously, cap those), then see if you can pull a vacuum on your system. The interior of the lines/hoses behave differently under a vacuum than under pressure.

My customer's 66 'Stang had a short line (1yr old) that was collapsing inside & doing just about the same thing, but at random intervals.
