Radium Fuel Pump Outlet Adaptor — 6AN Male | Walbro 460 / DW400 / Bosch BR540

This adapter converts the hose-barbed outlet of many high-flow fuel pumps to a 6AN male fitting for clean AN hose integration. Two billet aluminium adapter halves clamp tightly around the pump outlet and are secured with stainless steel bolts. A stainless steel retainer and Viton O-ring provide a positive, leak-free seal. All components are E85 compatible.

20-0298 Identification: This adapter is identified by a green upper fitting. It is designed to be as short as possible without sacrificing flow — 0.42" shorter than the 20-0599 variant.

Important: Before purchasing, inspect the pump outlet plastic hose barb ridges. Damaged or non-round barb ridges may prevent the O-ring from achieving a positive seal.
