1941 vacuum advance to manifold broke..

[hombres ruin]

Hi guys the vacuum advance connection to my manifold broke see pic . Do I need an exact one if so is there anyway I can get one or does anyone want to sell me one.. or can I use a connection with the same thread and out let part. Does it need that diaphragm ? It's a stock 41 ford engine and stock rebuilt Holley 94. Stock igniton with one of skips coils. Thanks guys

I just found a couple, PM me and I'll give you their emails, they might have another, you can't repair it ?

Not that it really maters, but that's a vacuum brake, not a vacuum advance fitting, correct?

Jseery well this fits into the manifold and the line from the distributor connects to it as well. I haven't dealt with this before so I may be wrong as to what it is but I cannot find this part anywhere. So I need to know if I can do something else if I can't find it. Any help would be great. I have included a pic as to its location . Thanks

If it's a front mounted distributor, then it's a vacuum brake line. The vacuum regulates a piston in the distributor. Might check with Bubba and see if he has any parts. There are other suppliers of NOS parts that frequent the Barn.

The posted photos are not specific to your year distributor, just a typical flathead distributor so you can see the parts involved. The vacuum line runs from the vacuum brake to the vacuum fitting near the carb.

Ya I had one of those on a 42 tudor that i had. Soft metal/pot-metal that broke when removing. Its a hard to find piece. I always assumed it had a diaphragm inside for the wiper. Ran a regular fitting after (no wiper), car ran same. .40 over "Stock" engine.

The broken part he is holding is a vacuum check valve for the windshield wiper.

It also serves as the banjo bolt for the distributor vacuum line. My 41 has the same fitting and I use a separate check valve under the dash for the wipers since the diaphragm in mine is long gone and you can see straight through the part.

As others have indicated, any cross drilled fitting will do the same job providing you install a separate check valve in the wiper's vacuum line.

The broken part is p/n 11A-17595 and is a silencer for the wsw vacuum supply. No check valve in there. Hard to fin part but do show up on Ebay at times. Dealers with NOS parts also have them some times.

So it seems I can use any drilled fitting with the correct thread and put the banjo fitting onto the bolt to the distributor and it will work. I am not running wipers at all so I don't need the check valve.. I am I correct or am I missing something . Thanks guys

[Tinker]

That is correct.

[JSeery]

You got it, and if all else fails you can just run a line similar to a brake line or metal fuel line between the distributor and the manifold and get away from the banjo fitting.

Great!! Thanks so much for the help and clearing up the issues and providing great advice. I will see how it all goes.. thanks again

So I found this banjo bolt to go to the manifold and onto the vacuum line. Question. This bolt has one hole in the non threaded side and not two like the original .. does that matter at all? Second if you look at the pic the new bolt has a smaller hole opening. Does this matter as well, or do we just need a channel for vacuum regardless of the size?

Here is one that I have.

That's it. With the wiper check valve. I ran the bolt I have and it all worked great no problems at all
