🚨 FORD F-550 FUEL LEAK 🚨

This Ford F-550 came in pouring fuel.

After getting it in the shop and tracking down the leak, we found the culprit a failed O-ring on the fuel source line.

A small O-ring can turn into a BIG fuel leak quick! We got it repaired, cleaned up, and ready to get back to work.
