Happy Labor Day
Received confirmation Friday carbs are safely in California (JIT for a holiday!) 

Looking forward to the return next week and putting some fire in this old FJ!!

Well I'm back after some life interruptions, and have a couple questions - Carb re-install is happily commencing but...

What's supposed to be attached to the nipple on the bottom of the tank?

And, in the group of miscellaneous bits, parts; what are the oval shaped thingies - also two groups of three screws, does anyone recognize them?

Also, can anyone identify the screw with the shoulder on it and where does the metal sleeve belong?

Ok, I’ll play...

The oval washers fit in the rubber grommets that hold your tank to the frame.
The (2) 10mm head bolts below fit thru the oval washers.
I am surprised at this question.....have you ever had your tank off?

The bolt with the shoulder and grommet goes to your valve cover.

The 3 JIS screws go to the snorkel on your air box

The 3 10mm head, short bolts attach your battery box.

The steel collar goes thru the grommet (2 grommets total) that attaches your gauge cluster to the fairing.
The collar can also go thru the grommets that attaches your fairing to the frame and the fuse box lid to the side panel and the oil cooler grommets.

The fuel tank nipple goes to a vent tube within your tank that draws off fuel vapors and allows the vapor to be pulled to 2 charcoal canisters as part of the California vapor recovery system.

What do I win? A jelly donut?

Thanks Joe, but....I might be wrong on those air box snorkel JIS screws.....it’s been so long since I’ve had a air box....those threads on the snorkel screws may be a course sheet metal type of thread for biting into plastic, not the fine thread shown in the picture...I can’t remember now....I do remember there are 3 of them.

Ha! No jelly for me....
I missed seeing that bolt with the shoulder and grommet is not a 10mm bolt head at all....it’s a JIS screw!

Robert gets this one....

That grommet bolt is for the timing cover in that post.

Thanks Pat,
I should explain, the bike is the proverbial basket case.  I came by this as a partially disassembled mess!  

These fasteners were laying in the left side cover for the pickup coils and the old tank had been removed and replaced with one that didn't have the inside all gunked up

Couple pics of the previous tank to see why it had to be tossed...

So, can I cap/tape off the nipple on the bottom of the tank?

The vent nipple and vent line should normally be dry, but a splash of fuel could get in the vent inlet, so to be safe I would cap it off. It’s a hot location above the engine so get a thick heavy wall cap.
Now, be sure your tank cap can draw air, this is needed as the fuel level in the tank drops.
You can tell when you open the cap...if there is a sucking type of vacuum when you open the cap, that’s bad.
You need to vent the tank cap.

Don't think this was California bike.  No vent line that I can see.  Thanks so much for the heads up on the filler cap though...

So I figured out that most of the fasteners are for the air box, 3 for the end cap and 3 others to attach it to the rear frame.

Also, what do the fasteners for the fairing vents look like?  And what is missing below and to the rear of the vent on the fairing?

You have a broken lower tab on your fairing that the air scoop attaches to...you should have 2 tabs, the upper tab is there but the lower tab is not.
There are reusable black plastic rivets that secure the scoop to the fairing.

RPM Robert....do you have a link? I could not find the rivets when I looked on your site.

The JIS fairing screw fits within the small oval recessed collar you show in your photo.
 (Shown in the photo to be right on the letter A)

You need this collar to spread the load on the fairing plastic and the JIS screw head needs to be recessed so the black fairing trim piece that hides the screw, fits flush with the surface of the fairing.

So, getting close to trying to fire this long asleep beast  I think I see why some of you have ditched the air box in favor of something else.  

The rubber tubes are not close to aligning with the carbs, so what do I do?  Prybar?  I've loosened the carb clamps at the intake a little but still no joy

Top two screws of rear frame section are out and still seems something is preventing air box from going low enough to line up with carb throats...
