injection fuel lines Perkins 4107

I am just completing the install of my rebuilt injector pump and need some help. When I pulled it out for rebuild I found some small black rubber cylindrical things about 1/4 inch high and 1/4 inch OD I shall call gaskets. When I was at the rebuild shop the mechanic told me they are fitted to the fuel filter inlet and return lines positioned on the end inside the injection pump. Since I only want to do this once I want to try to figure out their purpose. Also, I do not see them listed on the exploded view of the fuel line diagram items 11 and 18. Are they really necessary?
Thanks

I suspect if they have a purpose. These might be what you are talking about.

Re: injection fuel lines Perkins 4107

If they are fitted around the 1/4" or 3/16" copper fuel line inside compression nut then they are rubber ferrules instead of copper ones. Rubber, I was told was better for vibration. During my re-build in may this year, I put copper ones keeping in mind that they will wear out faster in presence of vibration. I have plenty of 1/4" and 3/16" copper ferrules, and compression fittings along with flexible copper line. Those are all good things to have spare for low pressure diesel fuel lines.

Yeah that is what they look like. Talked to pump rebuilder and he confirmed they go inside IP fuel in and return line. I want to be careful they go before Ferrell and not over the Ferrell.
