We have recently changed the oil in the forline pump, and since have not been able to get the MS portion to turn back on. When we do try to switch on the MS, the pump makes a loud gurgling noise and automatically switches itself off.

Any advice on fixing this problem would be appreciated! We are scared it is a fuse issue with the MS because we are not sure if we can find someone to service such an old model.

It sounds like you have a large leak that must be corrected prior to the turbo pump spinning up. Check all of your connections and make sure that there's secure and that the o-rings are properly seated on the vacuum lines
