Ben,
Welcome to the WFM forum and to owning a very fine and desirable tractor. I have two of these 322 tractors myself and would not part with either one.
One of the WFM sponsors here, Keeping It Green, lists a replacement part as Part #: M810617 as a substitute for the M802139 cap. It is $11.02 and can be mail ordered from them. You might also want to pick up a copy of the service manual for this tractor which is TM1591. I like the CD version for the search ability, but there is a print version available also. The CD costs half the print version, $55 versus $110. It really is worth the investment.
A lot of folks might think that this manual is expensive, but my owner's manual shows that in 1990 the service manual was $25.75 and almost anything of value has gone up about that same 2 to 4 times ratio in the intervening 19 years (or the dollar has gone down by a factor of 2 to 4...) This represents a compound interest rate equivalent of only 4% to 8% per year. Prices change over time and I recall 3 cent first class mail -- now first class postage is over 15 times that much.
(OK, off the soap box...didn't mean to start a rant, but the manual is REALLY worth having!)
The second yellow cap on the Yanmar engine is an alternative filler location for other applications, it is redundant to this motor location as the valve cover filler is easily accessed by simply raising the hood.
Again, welcome to the three cylinder Yanmar owners club...
