With most vehicles the pump lasts the life of the vehicle, but I replace more GM pumps within 100K than anything else.
If fuel pumps were not necessary, there would not have any on your car! If there is a problem with your fuel pumps, your car will not start, or it will start but it won't run for very long.
Normally they will last at least 100,000 to 150,000 miles but there is no guarantee they will last that long. A partially clogged fuel filter will shorten the life of the pump. Running the car until it runs of of gas will also shorten it's life.
No, fuel additives have no effect on the fuel pump. Fuel additives are really of no benefit whatsoever to your vehicle. The best way to help your fuel pump last for a long period of time is to change the fuel filter regularly. I recommend every 50,000 miles.
In most cases the life of the vehicle Try to keep fuel tank at least 1/2 full. The fuel pump uses the fuel in the tank as a coolant. A lot of failures are due to fuel pump overheating and shortening their life span
On average 13-18 years.
Water pumps generally last 60,000 to 90,000 miles. They are usually replaced around the time that timing belts are replaced.
Fuel pumps must not be too long because of the circulation of the gasoline. Too much can heat up the gasoline and cause performance issues and cause cavitation to the pump.
I have replaced 3 fuel pumps in my 94 Jimmy in the last 12 years. Problem is with the pumps. I replaced mine with Autozone pumps. I heard only factory OEM pumps last. Ones at auto repair stores like Advance, Autozone or Pepboys burn up quick.
On the in-tank fuel pump, or pumps if you have two tanks.
Earlier carburated vehicles used external fuel pumps.
Most fuel pumps for fuel injected vehicles will cost more than $100.00, U.S.
A fuel pump does that job.
