Hi! Are there any alternatives to a temp gauge besides the common additional gauge fitted outside of the main cluster? Anything out there that I can fit in the original gauge cluster slot? Willing to take tips on fixing the original unit too if there's no such thing as original style alternatives. Any guidance for a rookie would be appreciated.

So they are not meant to run in series if I want to use the carb with my 248 straight 8.

Quoting on this one where you recommend checking where the ports come out into the bore; I checked and here are some photos, one port is close to the venturi and one is next to the throttle butterfly. I highlighted the port near the venturi with a red dot. The port next to the throttle butterfly is, as you indicated, above at idle and underneath when cracking open the throttle. It seems to be connected to the factory port on the outside.

I will have to check the specs again with the seller I guess.

Son of a...biscuit.. okay, so this raises the concern that I may have the wrong carb that WON'T be a plug and play type of deal. Dammit. You learn something new every day.

Yes, it's the only port that I can see.

Thanks for the help. I will come back with an update once I get the parts I need. Hopefully this thread will be useful to someone else too one day.

The photo I posted is the actual line on my engine and original. Should be 1/6npt in size, correct?. And yeah, threaded female sleeve is what I will need with the conical seat inside. I wouldn't want to give up the existing port on the intake for the wipers as I still use the original mechanism and at one point I plan to connect the vacuum pump in series to that, so yeah. I will try to look for both 1/8npt and 1/16npt to eliminate any error. Thanks for your help! PS.: I do have a 40's style 248 replacement engine in it, hence the double action fuel pump.

Here you can see the exact threaded nut as the one you posted, must be a standard size across all series. NPT fittings are available to purchase in UK as well. So, to recap, at the carb end, the thread size is 1/8 NPT and the threaded vacuum line nut 1/6 NPT. To my understanding, I should search for a 1/8NPT to 1/6NPT female sleeved reducer/adapter.

I will have to check up on those details. I plan to run it on a stock engine. Thanks again for the help, I will await your reply.

Hi Bloo! Thanks for the quick response! In the photo below you can spot the vacuum port blocked off with a brass screw cap in identical configuration next to my carb. IT IS a brand new repro Holley. The carb in the photo is not mine, but it's exactly the same.

Hi! I want to fit a Holley 94 carb on my 248ci Buick 8, however I'm facing difficulty in regards to the vacuum advance line. The threaded end is too small to fit in the vacuum port that the Holley has. Advice on where I can find an adapter? Sizes would be helpful too. Many thanks!
