How Long Does a Fuel Pump Last in Cold Weather?

Fuel pumps are able to endure 100K-200k miles, but cold temperatures can limit that lifespan and put more strain on the system. Fuel thickens at cold temperatures, so in colder climates the pump willhave to work harder getting fuel pressure up around 30-80 psi. In colder regions drivers will usually observe fuel pump failures coming even sooner, sometimes as early as 80K-120k miles depending on vehicle usage and maintenance.

Fuel / Moisture – Weather ConditionsCold weather has the potential to keep moisture in fuel tanks and eventually corrode a fuel pump as well. In tanks, this can mean condensation vapors that turn into water droplets when the weather gets below freezing — and then rest in rusting puddles on top of pump components or plug filters. This issue is exacerbated in areas where winter temperatures often reach levels at or below 32°F, with vehicle owners recommended to leave their tanks even half full.

Some real world examples will illustrate this problem. For example, repair shops in Canada and northern U.S. states say they see more fuel pump replacements when temperatures plummet during winter months. The extra demand that is put on fuel pumps due to the modifications, as well potential damage from moisture further pushes replacement of the pump up in higher mileage.

Your engine may produce less power and use more fuel in cold operating conditions, as well — due to reduced efficiency of the fuel pump. According to automotive testing companies, cars driving in very cold weather can lose 10-20 percent of their fuel economy due partially to the challenges faced by a struggling fuel system trying just maintain proper flow.

Today as Elon Musk once said, the “artisan” of making things affordable is design and technology, which modern fuel pumps include advanced materials that can operate in arduous conditions where they are flawless although their performance could falter from extreme cold. Changing fuel filters and using fuel additives that prevent freezing can help prolong the life of a cold-weather-operatingt willImprovements: Fuel pumps滑稽补充更好 Writing by Ben Klayman; Editing By Zooey Zgutowicz, Gerald E.
