What's wrong?
The fuel hose on 2021-2022 Tiffin Phaeton and Allegro motorhomes carries diesel fuel from the fuel pump to the remote filter head on certain Cummins L9 engines. That filter head helps clean fuel before it continues through the engine. The hose uses quick-connect fittings, so the fuel system depends on the hose assembly staying tight and intact while the engine vibrates and heats up.
On affected motorhomes, the hose assembly has an inadequate design and quality problem. Fuel can leak from the hose between the pump and the remote filter head. Diesel fuel escaping in the engine area can contact hot surfaces and create smoke or fire.
People in or around the motorhome can see smoke before heat builds enough to start a fire. Treat smoke near the engine as the warning sign and keep the motorhome parked until Tiffin or a Tiffin dealer gives repair instructions.
Who's affected?
Covers the Phaeton and Allegro across the 2021 and 2022 model years, both tied to the same fuel system hose and fitting issue.

What's the safety risk?

- Follow the Tiffin owner letter mailed September 10, 2021 for remedy timing before scheduling service.

- Contact a franchised Tiffin dealer once the repair is open to schedule the free fuel-hose replacement that fixes the fuel leak between the fuel pump and remote filter head.
- Avoid driving with any fuel smell or visible diesel leak, and keep the motorhome away from ignition sources until Tiffin gives repair instructions.
What happens at the repair
The final dealer repair is still listed as under development, so the remedy should not be treated as ready for completion yet. Once Tiffin opens the repair, a Tiffin technician will replace the fuel hoses between the fuel pump and remote filter head. Parts and labor are covered under the recall. Tiffin has a general reimbursement plan on file for this campaign. If you already paid for a related fuel hose repair before the recall notice, contact Tiffin customer service at 1-256-356-8661 and ask what documentation is needed for a reimbursement claim.
