Yanmar Injector Seals

[Curt Sprenger]

Two of the Injectors are leaking fuel at the fuel rail on our Yanmar
generator engine. I contacted the local Yanmar facility. They show the
engine model number but with an added "CL" at the end of the
number...4TN82E-UK...4TN82E-UKCL. The shop's injector diagram and
location of parts is the same as the documentation that I have, but the
engine/parts numbers are different. The shop guy can't explain the "CL".
He contacted the US distributor and they think the parts are the same
and the numbers have changed over time. I've gone ahead and ordered the
o-rings and the copper seals. Good move or otherwise?
