Changed out my shutoff valve and all fuel line o-rings with viton today.

The o-rings on the end of the fuel lines which seal to the fuel filter housing (x4) are a different size than the typical fuel line o-ring.

Does anyone know what size those 4 are?

Additionally, has anyone measured the pre-filter o-ring or delivery valve o-rings?

For reference the OM606.962 uses:
shutoff valve 2.5mm x 12mm ID
typical fuel line 2.5mm x 8mm ID
