Good morning from Australia.
I have just inherited a 1927 Chev Capitol that has been partly restored.
I’m working on the Vacuum tank which is in surprisingly good order
However the two little valves that create and break the vacuum would seem to need reseating or resetting.
My question is: Can they be reseated? And how is it done.
Regards
J

Those little needle valves are fairly dependable. If the tank looks in otherwise good shape I just try to clean up the needles and seats with some spray lubricant and wiggle the needles into the seats.
Is your tank a 4 screw Stewart, or an 8 screw? The 8 screw uses an over center type mechanism that can be tricky. The 4 screw type tank is much less complicated but can have its issues.
If it needs to be rebuilt that service is available by one of the members that frequents this site.

Last year I had a problem with my 4-screw topped vacuum tank and chose to rebuild it myself. I did not do anything to the vacuum valves, but I did a bunch of other stuff. Here's the write up: Fuel system rehab for '28 Canopy ExpressCheers, Dean

I have seen two of the 8 screw type vacuum tanks fail with a dropped valve seat. I believe it was due to expanding die cast metal. One was fixed using some epoxy to reset the seat into position.

A loose brass valve seat on the 8 screw Stewart vacuum fuel pumps is relatively common. Most of us use "super glue" to put them back in place. Not aware of any that have loosened after that repair but if it happens another dose of "super glue" should put it back. Just be sure you push it fully back into the cover before the glue sets (only takes seconds!).

I wasn't going to say it because I have no follow up information about the longevity of the repair, but the other of the two 8 screw type vacuum tanks I mentioned was repaired with "super glue".
