Radium has used it on its fuel surge tanks since 2014, and it's the part you order when you're adding a port, replacing one that got damaged, or plumbing a pump outlet through the lid on a custom tank with a 9\/16-18 ORB hole.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eThe outside of the fitting is a standard 6AN male flare for a hose end. The bulkhead threads into a 6AN ORB port (9\/16-18 with an SAE chamfer) and seals on a preassembled Viton O-ring, which holds up to gasoline, E85, and methanol without swelling. Inside the tank, the 8.5mm barb takes 5\/16 inch submersible fuel hose from the pump outlet, clamped, which is how every in-tank pump in a Radium FST connects to its port. The fitting is anodized aluminum, bright-dipped green to match Radium's surge tank hardware, and because it's a bulkhead rather than a tee, the pump outlet, the lid, and the external line become one sealed path with no fuel exposed to the tank interior.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20-0170\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutside connection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6AN male flare\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBulkhead thread\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6AN ORB (9\/16-18), requires SAE chamfer in the mating port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInside connection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8.5mm (5\/16 in) hose barb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eO-ring\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eViton, preassembled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum, bright-dip green anodized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 fitting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadium fuel surge tanks, 2014 and later\u003c\/td\u003e\n\u003ctd\u003eDirect replacement lid fitting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCustom tanks and hangers\u003c\/td\u003e\n\u003ctd\u003eAny 6AN ORB (9\/16-18) port with an SAE chamfer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eNot vehicle-specific.

Lube the O-ring with a little oil before you thread it in and snug it by hand plus a quarter turn; ORB seals on the O-ring, and overtightening just squashes it. If you're replacing one on an existing Radium FST, the lid port is already chamfered. If you're drilling your own, the ORB port needs the spot face and chamfer, not just a tapped hole, or the O-ring extrudes. One per port; a typical surge tank lid uses several.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadium fuel surge tanks, 2014 and later\u003c\/td\u003e\n\u003ctd\u003eDirect replacement lid fitting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCustom tanks and hangers\u003c\/td\u003e\n\u003ctd\u003eAny 6AN ORB (9\/16-18) port with an SAE chamfer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eNot vehicle-specific.
