🔍 General Tank Inspection

• Inspect every 3–6 months for cracks, corrosion, or abrasion.
• Check weld seams, especially near brackets and fittings.
• Inspect straps, brackets, and vibration isolators.
• Look for leaks, fuel odor, or moisture around connections.

🧪 Interior Cleaning & Fuel Contamination

Contamination risks: water, rust, microbial growth ("diesel algae")

1. Drain tank completely.
2. Add high-alkaline cleaner (Simple Green or sodium tripolyphosphate).
3. Agitate for 30–60 minutes, rinse thoroughly.
4. Neutralize with a mild bleach rinse, then rinse again.
5. Let dry completely before refueling.

💡 Tip: Use a diesel biocide to prevent microbial contamination.

✨ Polishing Your Aluminum Tank

• Use jeweler’s rouge with a 6–8” muslin buffing wheel.
• Buff small sections and apply polish generously.
• Remove residue with acetone, lacquer thinner, or baking soda paste.
• Avoid abrasive pads or steel wool on polished tanks.

🛡️ Preventative Maintenance Tips

• Check cap seals and vents regularly.
• Drain sediment or moisture buildup (if accessible).
• Use fuel stabilizers and biocides during downtime.
• Maintain proper strap tension and isolation to reduce stress.

You may be able to repair tanks with:
