Metric on a Model T?
I ordered the fuel shut off valve that goes on the carb. 23T...I go to tighten the valve up with a wrench. What the heck size is this thing? Come to find out the nut to tighten is a 15mm..Is this legal? Will it still run? Disappointed..Tommy

Re: Metric on a Model T?
If the threads fit the fitting on the carburetor and packing fits the fits the fuel line, there shouldn't be any problem except that you should carry a wrench to fit in your tool kit when driving, just in case.

Re: Metric on a Model T?
There is a metric wrench in the tool kit already! LOL Think about it
I know the voices aren't real but damn they have some good ideas!

Re: Metric on a Model T?
When I lived in Holland, I had an English Austin. Because it had been in Holland since just after WWII, the nuts on the car were a mishmash of metric and Whitworth. I had lots of different wrenches.... (although I suppose you could also say I had both wenches and spanners.)

Re: Metric on a Model T?
My 1924 Morris has metric threads on all bolts and nuts with Whitworth heads on all bolts and nuts !!
It was actually quite logical; - due to a quirk of history (and a major world war) the Morris factory had been bought from the French and was tooled for metric threads but English mechanics were largely equipped with Whitworth tools and as the car was made primarily for the English market - so - easy fix!

Re: Metric on a Model T?
There are only 3 countries that haven't adopted the "International System of Units" SI system (aka metric system) the other two are Myanmar(Burma) and Liberia. The 15mm size has been popular for ever, almost 5/8 inch. Having owned several German cars, 10,11,13,15 and 17 were the most popular sizes. If you buy something Today you shouldn't expect to be made to US sizes. The population of the US is only 4.25% of the World's population. In other words there are more metric wrenches than SAE
The past is a great place and I don't want to erase it or to regret it, but I don't want to be its prisoner either.

Re: Metric on a Model T?
Australia went metric some 50 years ago No 15mm spanners was not a common size for us, although it would fit 1/4 whitworth. the most common one was 14mm which would fit 9/16" SAE and the 13mm would fit 1/2" SAE.

Re: Metric on a Model T?
Considering the US GDP is presently the largest in the world, changing over at this time would be unnecessarily costly. That said, after we're done Making China Great Again, in about 5 years the last 1/2 dozen or so functioning factories in the US will be in no position to NOT convert over.
If that nut is in fact 15mm, look at it this way: someone went to a lot of trouble and expense to provide this part to you. It is not a particularly common stocked size.

Re: Metric on a Model T?
I collect and sell spanners, and come across some interesting examples. From the chart above you can see that some metric/imperial sizes do roughly equate. However, in my gathering I have found some beautiful quality German Stahwille brand metric spanners stamped with both metric and imperial sizes. Try fitting a 12mm end on a 1/2" nut!
There is a blessing in metric conversion for model T's. Both 8mm and 10mm are oversize to imperial equivalents of 5/16" and 3/8", so these can be used to make clevis/hinge pins to take out wear in components.

Re: Metric on a Model T?
OK..big deal over nothing..just seems like everyone is concerned about original, so it struck me odd. New valve works great. I guess it didn't come with this valve anyway, so it really doesn't matter.

Re: Metric on a Model T?
May want to recheck ...
I’m too old to remember the why, but something mid 60s or so, Chevy, 327/300 horse, Corvette, took a 19/32” open end. I’m going to guess carb/head area. My tool kits thus have 19/32 wrenches ( but not my T kits.) I think you’ll find a 19/32 spins that valve fitting just fine?
The US had a mandate to phase in metric during the bicentennial year. Many large industrial company were already in a first and goal situation and then poof, just like that, somebody in early ‘75 said...never mind. (And by 78 or so we were getting cars that needed 2 tool kits)

Re: Metric on a Model T?
I’ve got a 1988 GMC pickup and most of the bolts are SAE but there are several 13 and 15 mm ones for some reason mixed in. I wear bib overalls so I take with me everywhere a small assortment of tools. I don’t know how people make it with only keys in there pocket because I’m pulling out one or the other for something all the time.

Re: Metric on a Model T?
The most important tool in the kit is an engineer hammer. It is designed to be used on all bolt and fitting sizes. One wack and the piece works. I find it best for carburetor adjustment ad float realignment.

Re: Metric on a Model T?
How dare you complain or mention a vendors part aint right? I call for the CCC (cancel culture council) Its unreasonable to expect a vendor to provide a part that fits your model T. It is not their responsibility. Heck, they lose &1.80 on every unit they sell & can only break even on volume. You should have paid more for it. It is your responsibility, as buyer, to make it work. Man up. You have options: make your own nut, grind that nut to fit your wrench, grind a wrench to fit the nut, plus a dozen other work arounds & excuses. We must be thankful to anyone who supplies us with parts that dont fit. I have already lost too much sleep over this post, i"m going to take a nap.

Re: Metric on a Model T?
For those who also have Model A's the original connecting rod nuts are 21/32 inch! Try finding a wrench that size.

I'll take this in a different direction.
You can use the original Ford shutoff valve. No metric.

Re: Metric on a Model T?
Corey, you can eliminate the screwdriver, needle nosed pliers and pen knife and add a pair of scissors, phillips driver, reamer and saw by carrying a Victorianox stainless steel multi tool. I feel lost without mine. my shifter is a 4" Sidchrome unit which opens to 9/16".
