My vacuum pump outlet. Last year I noticed the threads were nearly tore out of my outlet fitting on my gz vac pump. The case is very thin, what would you guys recommend I repair it with. It appears to be pot cast or aluminum. Maybe 1/8 thick. Want to take care of it this winter. Last year I just smeared some right stuff around it to stop the oil/water leaking. Pump works fine since its the outlet..

Thanks



Configuration: 3350#, 555 C.I.,

60 - 1.24
1/8 - 5.69@ 123MPH
1/4 - 9.03& 152MPH



3700#+210lb driver, FULL interior, through mufflers, 10.5 tire.
60'-1.333 (IN 4000ft DA! Joisy Math excluded; 1.25sec using JOISY MATH.) Wink

Buy a Moroso Vaccuum pump, the #1 choice of bracket engine builders and bracket racers, out selling all others combined!

That said, my friends nor competitors have never had this issue with their Moroso pump and neither have I on either of my cars. The Moroso case is far from thin and that's because it was designed and built for racing, unlike your pump which is a cheap OEM air pump modified for racing.

Although I'm sure that ^^^^ was helpful after looking at the pumps on their site I would just move up to the next pipe size for your A-N adapter. Drill and tap next size up. If it were me I would set it up in a mill though not free hand it.

If it is like most pumps you have to watch the depth of the fitting so don't tap too deep.

It looks like there are other options, but it would require machining and making parts.

Just buy a Moroso pump and throw that junk in the weeds. You can thank me when you see me.

Agree moroso pump best idea. Also understand not everyone has abudget that allows for buying new every time there is issue with something.

Drilling and tapping is great if you have material. If not you can try epoxy thread repair. I have use a few that work pretty good. I have also used marine tex which is basically epoxy but like steel once its set. Hell won a race with end of burnt out block filled with it. Make sure to use something for release agent or your fitting will be there for good. You could clean i9t out some and fill then retap it also.

None are super easy but cheaper than new pump.

Sometimes you have to cut your losses on fixing junk. I went through that with an Aerospace pump. I final went with a Moroso and have never had a problem since.

OK thanks - but not spending 400 dollars on something that is NOT going to pull any more vacuum than what I have. As mentioned it is on the outlet side and has zero effect on performance. Not to mention all the custom brackets I built so it would work on my setup.

The other fact I should point out is it was MY FAULT the fitting got messed up. My hood prop caught it and tore it out - not the pumps fault. Other than that my "junk" has worked fine for YEARS and many years on the street driving around. Still pulls full vacuum up to the relief valve setting.

The main question is what are some viable fixes - I have some like retapping but wanted to hear how others would go about it before selecting a path.

The path I offered was based on what most could do. If it were mine needing it I would make a saddle part that would match the od of the pump if it is on a radius. I would then drill and tap the body to match the pattern I put on the saddle part. The part would be drilled and tapped in the center for the original adapter. Easy peasy.

Thanks that is a good option. I have lathe and mill and a father that is a retired machinist. Sounds like a good project for him. LOL. Would fix the thin wall issue also.

Didnt want to warp the case and have it effect the ability to create vaccum.

Probably been 20 years since I could create enough heat for Tug welding.
