Assembly Correct Power B. Booster Check Valves
 

I think these were used up to 1970. Chime in if you know more?

2 check valves 1) has a very small crack some discoloration. 3 dots very clear 2) has a crack that actually goes perpindicular to the lip edge, so both sides of cracked area can be tugged a little and will move. I think super glue would fix it, hardly noticeable, 3 dots weak but money back if not happy. Both checked and work as they should.

1) $50 incudes ship
2) $35 includes ship. Paypal F&F ok. Thanks sYc.
