I tried to keep the stock pump, rebuilt it several times, but finally replaced it with a 24v electric. One tendency for the stock pump, is to put out excessive pressure. Actually, when I put in an in-line pressure regulator, cutting pressure to 3#, it ran better. Another tendency is for the lower vacuum part to fail, with associated leaks. Often it fails long before you realize it.

Never had a problem with the manual lever being in the wrong position. It should be spring loaded, and go to a neutral position. If it doesn't, probably needs a rebuild. The pump is not real pleasant to change - its time consuming. Otherwise, the vacuum part was a good source for leaks.
