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.
Water pumps generally last 60,000 to 90,000 miles. They are usually replaced around the time that timing belts are replaced.
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.
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.
My personal Experience is about 3 years. Ive had several pumps over the last few years. There are many variables to consider. Ie. Amount of use of unit, Length of use for pumps. Quality of care for the pump.
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.
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.
All fuel pumps make some noise. If the noise is much louder than other fuel injected cars your fuel pump is defective. Fuel pumps that make noise normally fail before long.
i came across a new site called gouldswellpumps.org and maybe you will find the answer on there as it is all about goulds well pumps and submersible well pumps
I just had the fuel pump replaced in my 1999 Blazer. Total cost with parts and labor was $700. This was with an original equipment GM fuel pump, which I would recommend (aftermarket fuel pumps are cheaper, but don't last as long...and when your fuel pump goes bad, you'll be stranded because the truck won't start).
By keepingit's fuel evenly distributed in the fuselage. Using transfer pumps to transfer fuel from one tank to another.
