Routine school bus fuel tank inspection is the fastest way to catch a failure before it becomes a safety issue. Tanks don't usually fail all at once — they give signs first.
What to Look for During School Bus Fuel Tank Inspection
The most common fuel tank failure point. Corrosion that has pitted through the seam will appear as discoloration or seeping at the seam line. Surface rust above the seam is normal. Seeping is not.
Corroded or Cracked Tank Straps
Straps that have deep pitting or visible cracking at the strap-to-mount connection are structural failures waiting to happen. A dropped tank is a road hazard. Inspect straps every time the bus is on a lift.
Fuel Odor Without a Visible Leak
If the bus smells like fuel but there's no visible seeping, check the top of the tank. Seeping at fittings and vent connections can run down the tank and evaporate before becoming visible on the ground.
Repeated Fuel Loss Without Route Explanation
Buses that consistently use more fuel than expected — accounting for route miles and load — may have a slow tank seep that isn't causing a visible drip yet.
Q: How long can a school bus run with a seeping fuel tank?
A: It shouldn't. Any active seeping is a fire risk and a safety issue. A tank that is seeping needs to be addressed before the bus returns to service.
The bus doesn’t wait. Neither do we.
