Note the position of the index marks on the filter in relation to a fixed point on the filter base. Note: There are rotation index marks on each fuel filter that are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten each fuel filter, use the rotation index marks as a guide.
Tighten the filters according to the instructions that are printed on the filters. Use the index marks as a guide. For non-Caterpillar filters, use the instructions that are provided with the filter.
