How cool are these! For perfect proportions, we turn them from big diameter stainless steel with a recess lip on each side to hide the gasket and move the bolt head closer to the banjo. We keep the wrench surfaces short, knocked the corners off the hex and rounded the bolt head too. They’re sized to fit both 5/16inch and 3/8inch hose, with plenty of fuel flow guaranteed. NOTE: To provide safe clearance with a 3×2 progressive linkage, banjo fittings must be used with our stainless banjo spacers (9086K). Will not provide clearance for progressive linkages on 6×2 systems. All direct linkages clear OK without spacers.
