🔌 Function

Holds a fuel-system component to its bracket or housing, keeping the mounting tight so the attached pipework is not worked by vibration.

⚠️ Common Signs of Failure

• A fuel-system component rattling or moving on its mount
• Fuel line chafing where the mount has shifted
• Screw found missing or backed out
• Head corroded so a spanner no longer grips cleanly
• Female thread pulled in the alloy housing

🛠️ Service Notes

• Check the length, thread and strength grade of the replacement against the screw you removed — engine fasteners are chosen for a specific clamp load, and a longer or softer screw is not a substitute
• Clean the threads in the component and make sure the mating faces are clean and flat before assembly; dirt, paint or old sealant in a joint feels like tightness and leaves the joint loose
• Tighten to the torque figure and the tightening sequence given in the workshop manual for your engine, working up progressively rather than pulling each screw down in one go
• Use thread locking or sealing compound only where the manual calls for it, and renew the locking washer, tab washer or nut that works with the screw
• Renew rather than reuse screws that are corroded, thread-damaged or visibly stretched, and any screw the manual tightens by torque-plus-angle
