Mike this pan hasn't been modified. The 10552 c pump is whats in there now with the .750 bore/ tube.
I had a HV55 with a .625 bore...............same problem
It may well BE the vac pump. I'm going to reduce vac , baffle the pump and very likely add an accumulator.
Moroso changed the Ultimate 2 apparently , because mine has a big kick out with tubes going through it ( 3 ) and a SCREEN not a baffle..........and it came this way new in 2001 or so.
