🔌 Function

The spacer maintains a fixed separation between fuel system components so that fasteners clamp to the correct depth and mating parts stay in their designed positions. Correct spacing helps preserve alignment and sealing across the joint it supports.

⚠️ Common Signs of Failure

• Visible deformation, crushing or flattening from over-torqued fasteners
• Corrosion, pitting or surface degradation of the spacer body
• Fuel weeping or seepage at the joint due to loss of correct clamping height
• Loose or repeatedly slackening fasteners at the assembly
• Misalignment or vibration of the mounted component

🛠️ Service Notes

• Refit the spacer in the same position and the same way round as it came out; many spacers set an end float, an alignment or a preload and are not simply packing
• Never leave a spacer out, substitute plain washers for it, or stack washers to make up a missing one
• Keep the faces clean, flat and free of burrs and old sealant, and check the spacer itself for wear, scoring or having been drawn down out of shape
• Where several spacers or shims come out together, keep them in order and refit them in the same sequence
• Tighten the fastening to the figure given in the workshop manual for your engine, then check any clearance or end float the spacer controls
