⚠️ Critical Safety & Installation Warnings
- Lube Rule: Use only silicone-based lubricants (e.g., Aladdin Magic Lube). Never use petroleum-based products like Vaseline, as they cause rubber to swell and fail permanently.
- Gentle Seating: After installing the tank clamp, tap it gently with a rubber mallet while tightening the nut to ensure the clamp and O-ring are seated uniformly.
- Manufacturer Note: This is a high-quality aftermarket replacement part. All manufacturer names and part numbers are used for reference purposes only.
