Recall 21V952 covers 140 2019-2021 E-One Quest Ii, Typhoon, Cyclone Ii, Cyclone N, and Typhoon N vehicles for fuel-tube cracks. Free dealer repair.
E-One is recalling 140 2019-2021 Quest Ii, Typhoon, Cyclone Ii, Cyclone N, and Typhoon N vehicles because fuel tubes between the fuel rail and injectors for cylinders four, five, and six can fatigue and crack and create a high pressure fuel leak. A leak near an ignition source raises fire risk, and E-One dealers will complete the recall repair free of charge.

What's wrong?
The fuel injector tube on 2019-2021 E-One Quest Ii, Typhoon, Cyclone Ii, Cyclone N, and Typhoon N vehicles carries diesel fuel from the fuel rail to the injector. The fuel rail holds fuel under high pressure, and the injector meters that fuel into the engine cylinder. The tube has to stay sealed while the engine vibrates and while fuel pressure rises and falls.
On these vehicles, the tubes feeding cylinders 4, 5, and 6 can fatigue and crack. E-One traced the problem to a mix of vibration strain, assembly strain, and material strength in the subject tubes. Once a crack forms, pressurized fuel can leak from the tube. The replacement tube adds a vibration isolator to reduce that strain.
Fuel leaks can be found during maintenance. An operator can also smell fuel or see a mist near the leak, which is the warning sign to stop and have the vehicle inspected.
Who's affected?
Spans five E-One fire truck lines across the 2019-2021 model years, all using the same fuel injector tube from the fuel rail to the injector.

What's the safety risk?
A high pressure fuel leak near an ignition source increases the risk of a fire. Treat fuel smell, visible mist, or a leak found during maintenance as a reason to stop operating the vehicle and arrange service. Keep ignition sources away from the leak area until inspected. Repair is free at any franchised E-One dealer.

What happens at the repair
At the dealer, an E-One technician replaces the fuel tubes between the fuel rail and the injectors for cylinders four, five, and six, then installs vibration isolators to reduce vibration at the new tubes. The replacement parts and labor are free under recall 21V952. E-One also has a recall-specific reimbursement plan for units not covered by the manufacturer's limited warranty. If you already paid for this fuel tube repair, contact E-One customer service at 1-352-237-1122 and ask what documentation the plan requires.
