Fuel tank
 

Hi all.
My car is Mercedes Benz E 240 1998 (Benzin). Recently, I replaced the fuel filter on my car and after two month passed, the filter was blocked and it was replaced again.
Now, I suspect the inside of the fuel tank is dirty and hence, I want the fuel tank to be cleaned/washed or its strainer to be replaced . Which one would you recommend to do in order to prevent the fuel pump and fuel filter from damaging/blocking.

It is so urgent. If someone answered for my question as much as possible, I would appreciate him.

A fuel tank (or petrol tank) is a safe container for flammable fluids. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine. Fuel tanks range in size and complexity from the small plastic tank of a butane lighter to the multi-chambered cryogenic Space Shuttle external tank.
