This DeatschWerks adapter converts a 6AN ORB male port into a 8AN male 37-degree AN flare connection. Read the direction carefully: the 6AN ORB end is the straight-thread, O-ring-sealed end that threads into a fuel pump, filter, regulator or fuel rail port, and the 8AN end is the flare end that accepts an AN hose end or flare fitting. The supplied O-ring does the sealing on the ORB side, so the fitting seats against the port face without thread sealant.
DeatschWerks lists a mirror-image part alongside this one, so match the number rather than the description: 6-02-0401-B is 8AN ORB to 6AN flare and 6-02-0405-B is 6AN ORB to 8AN flare. This listing is 6-02-0405-B. Ordering the wrong direction gives you a fitting that will not thread into the port on your pump or rail. Bodies are machined from heat-treated 6061-T6 aluminum and anodized matte black.
