The banjo bolts are undercut on the shaft at the inlet jet for high flow. The inside circumference of the banjo fittings are correspondingly relieved. The inlets have a patented unrestrictive stainless fuel screen inside. It’s not intended as a primary fuel filter, but as secondary protection from particles getting into the needle and seat area of the carburetor. They are held in place by a removable clip and can be cleaned with a shot of air.
