Spares?

[Pedro_The_Swift]

Had a bit of a cleanout yesterday and found these--
Exactly ten of the round seals and 12 of the rubber connectors.
The bus is a V10 and Isuzu did make a V12 in the same engine series..

Any ideas on what they are for?

What’s the part no. for the copper items? They look like injector seals.

Yep, could quite possible be injector washers...
and the other is definitely a "Leak Off" connector


but WTF is a leak off connector?
