I have one in my MGB and my TR7,both second hand from autojumbles,30or more years old.Steve..

There are plenty of the older Smiths type on Ebay, so I might end up with one of those. Eliminates the need for the additional 100 quid for the sensor.

Where does the vacuum gauge connect to?

 

Inlet manifold.

 

 

,,,,the Smiths sender is a separate £98 add-on, so I might decide it's useless before I buy and fit one;-)

 

Wholly cow - that gets expensive fast !

I can see why the TIM brand are well on offer.

If I can ask, why are you thinking about a Vacuum Gauge ?
 

 

Certainly Spider. Initially experimental to see if we can get more miles out of a tank. The Minispares Tim gauge is fairly cheap so I thought it would be an interesting thing to do. Then the more I read about it, it seems a more advanced one might be useful for diagnosing faults. Opinion seems split of whether they are worth the effort though.

 

 

You could temporarily mount a handheld type vacuum gauge so that you can do some testing. Once you get bored you can just remove it.

I assume a gauge like this also gets connected to the inlet?

Yes.

That's a similar gauge to those I posted on the previous page.

This is the one that I bought in the 80's (likely as a used gauge)

Hi Spider. There's a few of this type I've been looking at on eBay. Thanks for confirming. One comes with the insert in the picture. What would that be used for? Daz.

Sorry mate, the pic is a bit small for me to see what it is.

At a guess, I'd say it could be a 'barb' for connecting a hose to a threaded fitting.

[Rubbershorts]

I've just messaged the seller. Apparently, it's a restrictor that goes in the hose to stop the guage being erratic. Is this required on a mini? Seem to remember reading something on another car site that suggests it may not be.

It's not required on anything. Most people probably prefer slow steady movements on dash gauges so would prefer it to be fitted.

I was wondering of that was what it was, but foolishly thought better of it.

 

One would normally crimp down the hose until the needle steadied. I guess this is just a move elegant way.

Or put a mig welding tip in the pipe,choice of size holes available.Steve..

[Rubbershorts]

Morning all. Manage to get a 'new old stock' Smith vacuum guage so I'm now looking at fitting. The piping for it is exactly like the vacuum pipe that goes to the dizzy. Same dimensions and rubber type fittings. The manifold spacer on MS isn't deep enough for my spacing so I'm tempted to just drill out the one I have. Any tips on how I go about this, and where do I get one of those nipple things that is on the other side of the butterfly that the dizzy vacuum attaches to? Note, this isn't my carb, it's a stock picture to show what I'm after. Thanks, Daz.

You can get thicker spacers with the adaptor fitted.

Thanks Gazza. Deleted my first answer as I mis read your answer. I'm struggling to find anything apart from the Minispares offering.

I have a spare MS spacer with the barb/nipple on it if you need (you can take it out and fit it you your spacer?) - I bought it for exactly the same reason and it was too thin.  I fortunately had the nipple on the HS4 so just used that for the vacuum gauge.
