I don't know what you mean by so often. Change your fuel filter every 75,000 miles and you will be fine.
It has a permanent filer that is changed when the fuel pump is replaced.
How often should you change the fuel filter?
It could leak while the filer is off. Once the filter is back on, there should be no leaks.
The fuel pump is in the gas tank
Every 30,000 miles.
every 12000 miles
Every 2 years
It depends on how much you drive it. It could also depend on what type of fuel you use. You should change the fuel filter between 30,000 miles clear up to 100,000 miles. or if your car does not start and there is no fuel in the filter, then you can change it then.
I recommend every 50,000 miles.
Change it every 50,000 miles.
If you are getting no fuel, either the pump is weak and not pumping correctly or the fuel filer is clogged. Are you positive the pump is working? You should hear it run for a few seconds when you turn on the key and do not start the engine. Even if you hear it running it may be weak and need replacing. Change the fuel filter and see what you have then.
Every time you change the oil, which should be at least every 5000 mi, and more often for many vehicles.
