P/B Check Valve
Is this a correct P/B check valve for a 67? If so what other years was it used? If not whats it supposed to look like and what 's this one used for?
Thanks Bill.
Thanks Bill.

Re: P/B Check Valve
The JG text refers to this part (booster check valve) as a 'filter' and cites it's correct factory original configuration as having two concentric circles instead of multiple circles or an 'X' in the top center. There were several sources for these parts + early vs. late designs among the various suppliers.
My take is you'll probably lose points with this one being deemed a 'replacement' part due to its configuration of concentric circles. The earlier mid-year JG books provide better descriptive text regarding the check valve and most judges look for valves that have this configuration:
Two concentric circles with the inner circle having slightly more height than the outer circle...Last edited by Jack H.; August 25, 2008, 11:32 AM.
