When it comes to aircraft fuel systems, reliability is everything. If you're still flying with a Dukes fuel pump, you might want to consider an upgrade. In a recent video, Darryl Taylor discusses the benefits of replacing outdated Dukes fuel pumps with high-quality Weldon pumps.
Understanding the Role of Your Electric Fuel Pump
In many aircraft, including the Columbia 400, the electric fuel pump serves three crucial functions:
-
Priming the Engine for Start – It ensures that the engine gets the necessary fuel to start smoothly.
-
Backup Fuel Pump – If the engine-driven fuel pump fails, the electric pump takes over, ensuring continued fuel flow.
-
Low-Speed Pump to Prevent Vapor Lock – Helps maintain proper fuel delivery, especially at low speeds or high temperatures.
The Problem with Dukes Fuel Pumps
Dukes fuel pumps have been a staple in aviation for years, but with the company no longer in existence, maintenance and overhaul options are becoming increasingly limited. While there are still companies that can overhaul these pumps, they are prone to a common failure mode—leakage.
A telltale sign of a failing Dukes pump is the appearance of blue stains around the weep hole at the bottom of the pump. If you notice this during your pre-flight inspection, it's time for a replacement. The typical overhaul interval for Dukes pumps is around 10 to 12 years, but given the challenges in finding quality overhauls, a better solution exists.
Why Weldon Fuel Pumps Are the Better Choice
Weldon has been manufacturing fuel and fluid pumps since the 1940s, and their reputation for quality and reliability is unmatched. Based in Cleveland, Ohio, Weldon offers FAA-PMA replacement pumps for nearly all Dukes models. Use our easy to read application chart here.
Benefits of Upgrading to a Weldon Pump:
-
Cost-Effective – A brand-new Weldon pump is often less expensive than an overhauled Dukes pump.
-
Easy Cross-Reference – Finding the right replacement is simple with Air Power, Inc.'s online cross-reference tool.
-
OEM Approved – Weldon pumps are now original equipment on Cirrus and Cessna aircraft, a testament to their reliability.
-
Long-Lasting Performance – Built to withstand demanding aviation conditions.
As the saying goes, “Get the red out and put a blue Weldon in.” Upgrading your fuel pump is a smart investment in the reliability and safety of your aircraft.
