This 812MA Series replacement element kit contains one each of #8021 40 micron fuel filter and #8022 10 micron coalescer, with a lid gasket and T-handle O-ring.
The elements stack, one above the other, with the coalescer on the bottom.
Each unit requires one RK 22610 kit — so the 812MA requires one kit, the dual manifold 75812MA requires 2 kits, and the triple manifold 79812MA requires 3 kits.
