I need a spring model 77813 check valve
(Riegelwood, NC, USA)
I need a spring for the check valve. Sears reports that the check valve is no longer available. The spring has rusted away. As for comments for resolving an issue, I pulled the rubber grommet (seal) from the glycerin filled gauges and drained some of the glycerin as it had turned dark, preventing being able to see the dial. I did not drain all of it, just off the dial. I left the rest for vibration damping which is OK for up facing gauges.
