I need a sediment bowl assembly and a gas cap for my Series II D-12.  Does anybody have a good recommendation of an on-line source to get parts with some resemblance of quality? (not TSC crap).  Also a lot of the gas caps I see listed for the D-12 are not vented.  I tried a non-vented cap once and the tractor wouldn't keep running very long.  Is it supposed to be vented or non-vented?

The cap has to be vented. Any gas tank that does not have a vent built into it, needs a vented cap.

As far as the sediment bowl assembly, I know of none that are of better quality. I have changed several over the years and I see very little difference in quality in the aftermarket sediment bowl assembly than the original.

  As for the sediment bowls, It really doesn't matter what the packaging is, they all come for the same place. If you end up with a bad one, it just escaped the poor QC, try another.
   And yes it needs a vented cap that also allows the built up pressure to release, because when the tractor get up to operating temperature the gas in the tank has expanded more than you'd think.
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY
