⚠️ Common Signs of Failure

• Diesel seeping at a crimped end fitting or through the hose wall itself
• Fuel smell and dark staining below the hose run
• Air entering the low-pressure side, giving hard starting or an unsteady idle
• The outer cover found swollen, hardened or cracked
• Chafe damage where the hose has rubbed a bracket or another line

🛠️ Service Notes

• Check the length before ordering - this assembly is 730 mm and 20450662 is the 630 mm pipe
• Renew the sealing washers at the unions and refit every original clip, because a preformed hose only keeps its designed route if it is clipped where it was designed to be clipped
