⚠️ Common Signs of Failure

• Cracked or leaking tank
• Fluid level changing unexpectedly
• Damaged hose spigots
• Tank not venting correctly
• Loose mounting or vibration damage

🛠️ Service Notes

• Confirm the tank is the one specified for your installation and that its connections, mountings and cap or sender fittings match what you are taking off
• Mount it on its proper brackets and rubbers, fully supported, so a full tank is never hanging on its hoses or pipes
• Renew perished or distorted hoses, seals and clips, connect them without strain or tight bends, and check the pipe stubs are clean inside
• Renew the cap and its seal, and any gauze or strainer, if they are damaged — on a pressurised system the cap is part of the system, not an accessory
• Fill and bleed to the procedure in the workshop manual for your engine, then check for leaks cold and again after the first proper warm-up
