What is the purpose of the locating pin? Especially since it is not being used in newer vehicles.

Aerotanks in San Bernardino, CA has a pre-designed custom gasoline fuel tank available to fit old Dodge vans and motorhomes.
The tank is 40gal and mounts to the bottom of the frame. It includes mounting brackets and a new sending unit.
They build it on order, so you must pay in advance by check, money order or cash - no refunds if it doesn't fit so check your measurements carefully. They will provide a schematic on request.
Current price is $578 plus shipping.
As fuel tanks are getting harder and harder to find, it's good to have a source lined up. Just in case you run into a stupid rock.
I just got my new tank installed. They needed to finagle the top vent a bit to make it fit, and run some new hoses, but it works great. Filled it up with 41 gallons of fuel.
Between that and my "problem child" rear tank, I have up to 70 gallons of fuel. Although my rear tank won't always fill completely, so I'm back to using it as an "emergency" tank and a "get thee to the gas station" tank. ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")
But it went in nice and they had it done within a day. Took about 10 days for AeroTanks to build it and it to arrive at my shop.

As it was explained to me by the old-timer tire guy from whom I got the new-to-me 16" wheels, it was to ensure that the wheel coins lined up correctly and also so that the valve stems were in the same location and the inner stem was easily accessible.

Color me naïve. What's a "wheel coin?"
Valve stems--I should have thought of that.
Thanks.

The coins are the lips of the bolt holes and are convex and concave, allowing the inner and outer wheels to mate/sandwich together. The thought is that they won’t move around on the wheel stud, causing the bolt hole to elongate.

This explanation, especially in terms of valve stems, is the best I've heard so for.
The 'skirted' lug nuts in StingrayL82's picture have a conical indent that fits the outward coining. I like those lug nuts better than others you find on the same rims but both work equally well.
I think the fact companies are still putting the locating holes/slots in wheels is a case of "that's the way we've always done things." Some people have suggested the companies don't/didn't want to change the stamping dies. That doesn't make sense because that kind of tooling eventually wears out and needs replacing.

BTW - I wasn't aware that Ford rims had been changed from rounded slots to a round locating hole. The Ford rims I've seen, from the early 70's, had rounded slots just like the Dodge rims.
That's why I thought both were made on the same manufacturing line. So, maybe Ford got a different manufacturer at some point and made the change then.

toedtoes - Some motorhomes with dual tanks have a second fuel pickup in one tank (usually the rear) for a genset. The second (genset) pickup is shorter than the main pickup so the genset won't use all the fuel in that tank.

Yep. The clippers were built both ways - with genset and pickup; and without. Mine was built without. They also were all built with only one tank (front) - the rear tank is aftermarket and was not built for a genset.
All the fuel is used, it just doesn't always fill completely. Last fill it would only take 10 gallons even though it had only about 5 gallons left in a 36 gallon tank (holds 30 gallons).
Annoying more than anything, but with the front tank back up and running it's not a rear problem.
