Check your injector and ECU spec. Carbies need far less, usually 5 to 7 psi.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does ORB mean, and how is it different to AN?\u003c\/strong\u003e\u003cbr\u003eORB is O-Ring Boss: a straight thread port that seals with an O-ring, common on fuel pumps, regulators and filters. AN seals on a flare instead. An ORB to AN adapter lets you run AN hose to an ORB port.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size fuel line do I need for my horsepower?\u003c\/strong\u003e\u003cbr\u003eAs a rough guide on petrol EFI: AN6 is good to around 500 hp, AN8 to around 800 hp, AN10 beyond that. E85 needs about 30 percent more fuel, so go up a size if you are running it.\u003c\/p\u003e\u003ch3\u003eQuality and warranty\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMade in China, precision CNC-machined from solid aluminium, not cheap cast or pot-metal fittings\u003c\/li\u003e\n\u003cli\u003eTough anodised finish, clean threads and true 37 degree flares that seal properly\u003c\/li\u003e\n\u003cli\u003e2-year repair or replacement warranty against defects in materials and workmanship, on top of your rights under Australian Consumer Law\u003c\/li\u003e\n\u003cli\u003eSold and backed by Tucks Performance, an Australian-owned business.
