Seems mine is shot - will buy a new diaphragm from Tangerine, however, would also like to buy one if there is one out there in 914 land

Thank you in advance

Is the electrical side shot on yours ? Did you run both the vacuum and electrical checks?
Do you know the correct PN for a 74 ? I have a milk crate full of MPS's. Since you are rebuild it the vacuum should not matter. Most leak.

The electric side is good, the diaphragm is broke from putting pressure rather than vacuum on the pipe.........my vacuum gun has a dual valve which was in the wrong position when I was testing the device.......sigh.....

Would be interested in another one if you have one for the 2.0 ('74) that does not leak too much.

Thank you, BD,
