⚠️ Common Signs of Failure

• Diesel smell in the engine room and a damp or stained hose end
• Hard starting, surging or an engine that will not hold revs as air is drawn in through the hose
• Hose gone hard and cracked, or swollen and soft where fuel has attacked it
• Ferrules or clamp bands corroded at the hose ends
• Chafe flat worn into the outer cover where the hose has rubbed on a bracket or pipe

🛠️ Service Notes

• Renew the sealing washers on the hollow screws whenever the hose is disturbed - they are the usual source of a weep blamed on the hose
• This hose belongs to the alternative pump and filter mounting layout, so confirm which arrangement the engine carries before ordering
