Hi,
I also posted this exact same thing in the FAQ forum. But, there have been a couple recent posts on the Late Model board here where this info might be useful. So, now you can see these nice pics in two places!
Or, what is *supposed* to be in a JD350 fuel tank! More often than not, this stuff is missing. I got lucky when I bought my 78 JD350C from Mark a couple years ago. This stuff was actually still in place. Actually, everything was still in place and the machine not all beat up.
So, the first thing is the vent tube at the bottom of the tank. There are always posts about machines that run at first and then die out. This tube is a vent that passes from the bottom all the way to the filler opening just under the cap. This lets air into the tank to replace the fuel as it is drawn out. Well, when it isn't plugged up, anyway. This is looking at the bottom of the tank from the rear of the machine.
All the other shots are from kneeling on the seat looking back at the tank.
Next, we move up top to the cap. Notice the nice rubber gasket. This, so fuel doesn't slop out up by you. Often missing to vent the tank because the vent tube is plugged....
Next, we have several parts. A dipstick, a retaining ring and a filler screen. You can see the vent tube.
This is the dipstick. Passes thru the hole that isn't the vent. The bigger one that is actually part of the filler screen. So, if the filler screen is missing, you won't have the second hole. Let's you check fuel level.
Here is a better look at the upper vent tube. The shiny one, not the black one. It is easier to pass a cleaning wire from the top down to the bottom.
This is the ring that holds the screen in place.
This is the fuel fill screen to catch some junk before it gets in there to begin with. You can see where the dipstick goes alongside the screen.
This is the filler opening missing all the parts. All you see is the upper vent tube.
Hope all that helps!
Stan

Re: What is in a JD350 fuel tank
Thanks for the great pics and info Stan!
Had the issue with plugged vent on my 450B.
I fumbled along and finally found the vent. It’s nice to have this for others to reference.

Re: What is in a JD350 fuel tank
Hi,
It has been pointed out to me that, once again, these parts weren't in place in the beginning. They were added as a running change as the years went past. So, an early 350 didn't have the strainer or the sump drain. I know the straight 350 I once had didn't have a strainer. I just figured it had 'got gone'. Well, it is the sort of thing to be yanked out and tossed.

Re: What is in a JD350 fuel tank
Good pics Stan!
Also note that somewhere (350B?) along the line they also added an outlet screen.
It threads into the pipe nipple that leads to the shut off valve, only way to clean it is to drain the tank.
Another less important item is they added the lockable cap too (or at least the arm for a padlock).
The sediment trap is one of the reasons they switched to the rotary valve on the winch on the later machines.
It interferes with the spool style setup
