I agree it isn’t stock for early tanks. As I mentioned in my previous post, H-D introduced the first female fuel valve for 1975 models.

Far as I know... 1974 SuperGlide Tank was first Straight thread external thread Bung...all previous were female Pipe Thread... others???

 

Three pages below are from my 1971-84 H-D FX Models (FX, FXE, FXS etc) parts catalog. Notice fuel valve assembly #62125-55B was available to be used for 1971-74 models.








Fuel valve assembly #62125-55B also appears in my 1941-84 H-D FL Models (FL/FLH) parts catalog and it was available to be used for 1966-74 models.

A similar type of fuel valve was used as far back as late-1950 when it appeared on the Model S 125cc single cylinder. At that stage it was #62125-50.


My 1971-84 FX Models catalog and my 1941-84 FL Models catalog both indicate fuel valve #62129-75 did not appear until 1975 models.

Well don't know what to tell ya about all that... Question tho
what is the First year of the SuperGlide Tank????
Have ya ever seen an O.E. SuperGlide tank with a Pipe thread Bung???
Please show it...
Even tho I did Not buy my '74 FX [no E] new... My brother did... and he did Not do many changes until he decided it needed to be an FL... Nother story!!!

 

First model year for the one-piece Super Glide fuel tank was 1973. It’s described as a ‘Rakish' new tank in the ad below.



The bike in the ad above appears to be an early-73 and next is another example. Notice the small tail lamp. Also notice no indicators.




Late-73 SGs had indicators and a bigger tail lamp of a new design.

If you mean the type of one-piece SG tank that accepts a male fuel valve, then yes, I’ve seen lots of them. They began with 1973 models and continued through 1974 models. If you do a Google search you’ll find plenty of examples.

^^ Those sure look like '74 Adds to me... but... can't tell by appearance..
And I guess I have Never seen a pipe thread bung for the old Male petcock on any SuperGlide Tank..
Maybe my Google Foo is not equivalent to yours...
Again... my brother bought his 1974 SuperGlide new... still here on the Farm... Straight [female] new style Petcock...

BTW ... By most accounts, 1974 was officially the First year of the SuperGlide Tank ..Tho the one you show certainly has the 1973 Brake... Odd indeed...

Maybe some Models got the new Tank...with the Old Brake??? Never seen that one before....Interesting Brochure certainly...

 

Those two ads are not 1974. They are 1973. The graphics on the fuel tank are one of the things that help identify those two Shovels as 1973 models. You’ll even see similar graphics on the helmet in the first ad. It was not uncommon for H-D to use helmets with those graphics in ads for 1973 model machines.

In January 1973 an article on the 1973 Super Glide was published in Cycle magazine. Below is the front cover. Notice the fuel tank has 1973 graphics.



Next is a picture from inside that Cycle magazine. Notice the fuel tank has a male fuel valve assembly (#62125-55B). Even visible is one of the fuel valve *****.

^^ That explains the 1973 Brakes... and the Pipe thread petcock is obvious...and the only one I have ever seen...
Very Interesting that even around the Harley dealer that sold that 1974 Superglide to my Brother... and Most people, including me ... believe the '74 was the introduction of that tank...
The MoCo Decides... and did... Not Us... Glad you have that Brochure...
Confirms a couple other thing in my mind.. like why the 1974 FX shifted upside down... and approximately when the Thru the primary shifter was introduced... I always believed 1973!!!

Dannit... Now I gotta go find the "dash" number on that '74 Shift drum...

 

What’s the deal with that shifter? Would it not reverse the shift pattern like that?

 

That was Harleys idea of Mid Controls in the day... I'm trying to discern when the Upside down drum was Began...
Knowing the 1974 was indeed one up and 3 Down.,,, the photo got me to wondering if the MoCo somehow decided that the SuperGlide should be like that... and stayed that way.. like the right side shift Sportster, until the Govt. decided to protect us from anything not Japanese and get in step with the way the Japanese Motorbikes did things!!!

Actually... thinking about this... the upside down Drum, would have made the Early SuperGlide one Down and 3 up... so... I may have answered my own question???? Maybe
I really do need to get at least the dash number off that drum....
