What's wrong?
The fuel pump sub harness on the 2016 Triumph Street Twin is the short wiring section that carries power to the fuel pump inside the tank. The pump uses that electrical feed to move fuel from the tank to the engine. Because the harness passes through a fuel environment, its sealed plastic connector has to keep fuel inside the tank and away from the main wiring harness.
On these motorcycles, the potting compound used to seal the molded plastic parts does not stop fuel from passing between the parts. Fuel can enter the wiring, travel along the harness, exit the tank area, and drip from the connector at the main harness. Triumph's remedy replaces the fuel pump sub harness, part T2401414, with part T2401554, which does not use that compound as the fuel seal.
There is no warning sign before failure. An owner can first notice the problem only after fuel has already traveled through the harness and reached the connector outside the tank.

What should I do?

- Contact a franchised Triumph dealer to schedule the free fuel-pump-harness inspection and replacement that addresses the damaged in-tank wiring and fuel-leak risk.

What happens at the repair
At the dealer, a Triumph technician inspects the fuel pump harness and checks its batch number. If the harness is in the affected batch or shows the covered condition, the technician replaces it. The inspection and any replacement parts and labor are free under the recall. Out-of-pocket fuel pump harness repairs before the owner notice are handled through Triumph's limited warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you've already paid for this repair.
