What You'll Learn
Fuel pump replacement can increase fuel economy by 2-3mpg
For example, one user reported that after replacing the fuel pump in their Civic, their fuel economy jumped up by 2-3mpg. They also noticed an increase in power, and that running the air conditioning no longer affected their fuel economy as it used to.
It's worth noting that some vehicles get better fuel economy in warmer weather, despite running the air conditioning more. This is especially true for shorter trips, where vehicles go ECM closed loop sooner, oil/transmission fluid is thinner, tire pressure rises, and there is less air resistance.
If you suspect your fuel pump is failing, it's recommended to have it inspected and replaced by a qualified mechanic to restore your vehicle to its peak performance. The cost of changing a fuel pump will vary depending on the vehicle's make and model, the type of fuel pump required, and labour rates in your area.

Another user suggested that some vehicles get better fuel economy in warmer weather, despite running the air conditioning more. This may be due to a combination of factors, including the vehicle going ECM closed loop sooner, thinner oil/transmission fluid, increased tire pressure, and reduced air resistance.

Fuel pump replacement can improve engine startup
A user on BobIsTheOilGuy replaced the fuel pump in their Civic and noticed a jump in fuel economy of about 2-3mpgs, as well as more power. They also noted that running the air conditioning no longer affected the fuel economy as it used to. The user attributed this to the new fuel pump's ability to meet the engine's fuel demand.
Other factors can also influence fuel economy, such as warmer weather, shorter trips, and the shape of the vehicle. For example, older SUVs tend to have less air resistance, which can improve fuel economy. Additionally, in warmer weather, the oil and transmission fluid become thinner, tire pressure rises, and there is less air resistance, all of which can contribute to better fuel economy.

Fuel pump replacement can reduce fuel consumption
One user reported that after replacing the fuel pump in their Civic, their fuel economy jumped up by 2-3mpg. They also noticed an increase in power, and that running the air conditioning no longer affected their fuel economy.
Other factors that can affect fuel economy include the weather, the type of vehicle, and the length of the trip. For example, some vehicles get better fuel economy in warmer weather, especially on shorter trips where they go ECM closed loop sooner, oil/transmission fluid is thinner, tire pressure rises, and there is less air resistance.
