Anyone have a source for Brake Master Cylinder filler caps p/n 9510292 for the master cylinders. Tried a new set from Parker Hannifin p/n 140-01900, but these don't fit.

Thanks,

Thanks,

Bob, while not the same part #, Spruce has the "P SERIES THREADED CAP PLUGS". They're "plastic" NPT & come in several sizes to fit the application (1/8" NPT for the G'year cyl as I recall). I don't believe they're "vented" but it's simple to drill a vent hole. Hope that'll help...and, hope all's well with you, old friend!

Thanks Mac! I was on Spruce earlier and didn't see these listed.
