Fuel Pump Nipple Guard. Certain KTM, Husqvarna, and GASGAS TBI and EFI models use a small plastic fuel-pump outlet nipple that is extremely vulnerable to side load, rock strikes, and tank installation pressure. If that nipple breaks, the bike instantly loses fuel pressure and is dead on the trail. The Bullet Proof Designs Fuel Pump Nipple Guard reinforces and shields this fragile area with a CNC-machined 6061-T6 billet aluminum support. It prevents cracking, impact damage, and over-rotation of the fuel line during tank service. Designed to fit perfectly under the tank with zero interference, this guard is an essential upgrade. Key Features: Prevents the fragile fuel-pump nipple from breaking. Protects against impact, side load, and tank installation stress. CNC-machined from 6061-T6 billet aluminum.
