Brake Booster Check Valve

I can't be the only person with this same problem, but I have found nothing that fits right on my 1967 with the single 11" booster. I wanted to get a new valve and the only thing i see is the Dorman 80189 which has a grommet fit inside of another grommet with no lip to keep everything together. This just looks like a leak waiting to happen. The other that shows up is a Raybestos 89000 which just looks small. The booster has a 1-1/16" hole and the old check valve is a lot bigger than all of these aftermarket ones. I found a few reproductions for a Mopar or Ford but it has two inputs. Was this year just an odd size hole on the booster?

They seal very well once it gets evacuated. Additionally there are in line check valves that plug directly into the hose instead of the booster or the manifold.

I assume your talking about the Dorman ones?

The in-lines I saw where on cards on display at the front counter of my local Chinese parts store. I go in there to get lubricants and small parts such as fasteners to replace things I though I had in inventory, but it either fell out of it's blister pack or other wise was misplaced (I hate squirrels, they are rats with furry tails and get into everything).

The inline might be just as much of a pain trying to find a grommet that fits the hole. i will keep digging and see what turns up or just try the Dorman.

In-line has a hose barb on each end. It just pushes into the half inch hose.

Correct but wouldn't you need to replace the old check valve rather than just leaving it in place?

If it isn't leaking to the atmosphere you could leave it in place. Usually the piddle valve inside wears out and breaks, not the exterior body of the valve.
