This rubber fuel hose elbow connects the fuel line between the tank and the injection system on the host tractor. It is positioned in the low-pressure section of the fuel circuit, where it routes fuel around obstacles and absorbs vibration from the chassis. The elbow is molded to maintain a consistent internal diameter through the bend, preventing flow restriction that could cause cavitation at the lift pump. A cracked or softened elbow allows air ingress, leading to hard starting and erratic idle. As an original AGCO component, the rubber compound matches the original material specification for resistance to diesel fuel and under-hood temperatures. On replacement, ensure the hose clamps seat fully on the straight sections and that the elbow is not twisted during installation.
