Foil tag on vacuum enrichment diaphragm

[Doug Y.]

I am not sure at what position on the clock that the foil tag on the vacuum enrichment diaphragm should be mounted. Hoping that the fuelie gurus might be able to help me. My unit is a 7017380, 1965. Many thanks in advance. DCY

Re: Foil tag on vacuum enrichment diaphragm

Doug, Your post question almost make me click on buy.
So you are asking about your 65 FI triangle inspection tag location.

A typical location for it according to old pics and original FI's I have seen is this. 12:00 screw on the enrichment diaphragm cover that is held on with 5 blackened fillister screws.

Now for many years it was OK to put it on the 10:00 screw as per an article written in the "Restorer" and some judging manuals. Personally I like this for the midyears as it helped protect the delicate tag from bending.
But it was not correct. On my 63 though that's where I put my original tag as it's my pride and joy and fagile for sure.
Recap: for 63 to 65 = 12:00 screws.
For 58 to 62: 10:00 screw
For 57: I don't know.

Re: Foil tag on vacuum enrichment diaphragm

Thank you John for the reply, I was hoping that you would respond. I will put the tag at 12 oclock. PS I am now the happy owner of a unit that you professionally restored and calibrated. I purchased it from a fellow in Baltimore. It is almost too gorgeous to put on my new engine. I earlier purchased an anti siphon valve for a '63 unit from you last summer at Carlisle. I am sure I will see you again in August. Rgds DCY

Foil Tag location on the 1957 Nassau car. 4360 unit ( pre RPD tag ) stamped 132. I wonder how many original foil tags remain for these very early pre RPD tag units? Foil tag is also stamped 132.

Re: Foil tag on vacuum enrichment diaphragm

Joe, Now that's a neat photo. Personally I have never seen a 4360 triangle inspection tag.
You could stare at that pic for an hours. That's a very early unit. A pal of mine has #16 though. But he doesn't have the foil tag.
To bad the old racer didn't have the matching air cleaner though. You would expect to see a louvred one especially on a unit and car that early.
But they weren't that great especially for racing. Thanks very much, JD

when I get a chance I will post a picture from the other side.

Actually the air cleaner on this unit is much rarer than the
multi louvered one. The one on this unit is one of only two
known to have existed. The other one was on the Bill Mitchell SR2 at
Sebring 1957 when it was converted to a fuel injected custom
air box car.

My Nassau car may have been a prototype air box car but
not enough evidance has been produced.

Notice the special pressure check valve on top of the. Fuel
meter, only known to exist on the Nassau cars

pretty neat

WO 17792 MAY have some.

Art...care to elablorate.

I don't know of any printed or photo evidence that has surfaced on the test bed cars for the Air Box option. Certainly they do exist as the option had to be tested. I wonder if it was tested at Smokeys garage by Smokey, Ralph Johnson and Dale Swanson.

Since there was a version made for the big Chevy NASCAR blackwidows..I also wonder if the air box was developed or tested at SEDCO.

The Bill Mitchell SR2 although a custom air box was installed for the March 1957 Sebring race...so I am thinking this all took place between December 1956 and March 1957...with Bill Connells May built St.Louis Air Box car possibly being the first production air box car.

Nope, the Work Order speaks for itself.

Here is another example in a different location.

Re: Foil tag on vacuum enrichment diaphragm

Joe, When you put up the first pic I thought the air cleaner looked different for sure. The air box car used a different air cleaner element than a typical 57 FI car. In Nolands book I remember seeing the part number for the air box element.
Need nice close up of a 4360 foil tag. I heard that a 4360 tag does not have the paper punches in it like the 4520 tag does. But that is heresay. John
