How To: C15a Wire-3 restoration

Hi Jordan


Took a while to find it but here is the Service Bulletin I was remembering.

Interesting the addition of flex lines not found on earlier CMPs. Just shows why we find all sorts of configurations on things on CMPs as time goes bye that are not necessarily shown in the manuals. It is interesting that these little change do show up in the parts books.



Bart Vanderveen was able to narrow down the date of construction of certain CMPs by what combination of special or different parts using the different dates on of publication for the parts book.


Looking through the parts book it will have little notes like "after serial number ?????? use part number ?????." But then again you can find a particularly early CMP that has every single update done to it.


Cheers Phil


PS- What did you use to seal the gasket around the fuel gauge sender unit? The ethanol containing gas has plagued my trucks with weeper leaks that come and go.
