Inspecting Mobile Fuel Tanks for Structural Damage
A systematic approach to identify issues like cracks, corrosion, or deformations that could compromise safety or fuel integrity
1
Exterior Visual Inspection
Cleaning and Preparation
- Clean the tank surface to remove dirt, fuel residues, or debris
- Ensure all areas are visible for proper inspection
Surface Examination
- Check for cracks along seams, welds, or molded joints
- Look for deformations such as dents, bulges, or warping
- Inspect metal tanks for corrosion spots, rust, or pitting
- Check plastic tanks for discoloration or brittleness
2
Openings and Connection Points
Critical Components
- Inspect fuel fill neck, outlet valves, and fitting ports
- Check for cracks around bases or signs of loosening
- Examine seals around caps or lids for damage
Mounting Hardware
- Ensure brackets and mounting hardware are secure
- Check for bending or cracking in support structures
- Verify that all connections remain tight during transport
3
Pressure and Leak Testing
Pressure Test Procedure
- Seal all openings except one and apply gentle pressure
- Stay within the tank's recommended pressure limits
- Listen for hissing sounds indicating air leaks
- Use soapy water solution to identify bubble formation
Alternative Methods
- For non-pressurized tanks, partially fill with water or fuel
- Let it sit and check for dampness or drips
- Inspect the area beneath the tank for any signs of leakage
4
Internal Damage Assessment
Direct Inspection
- If accessible, check interior for rust or sediment buildup
- Look for material flaking inside metal tanks
- Inspect plastic tanks for internal warping or layer separation
Indirect Assessment
- Monitor fuel quality over time for sudden contamination
- Check for sediment in fuel suggesting internal damage
- Note any changes in tank performance or fuel integrity
