    Hi, kaukau. Sorry to hear about that. How many miles does your car have?

    OK.

    Have you replaced all fuel filters?

    Those in the engine bay and the one in the fuel tank (screen filter)?

    I changed the filter in the engine compartment. I did not clean the fuel pump in the tank because the pressure on the filter in the engine is 1.5 bar.

    I was looking for a spare part for the type of car and the pressure on the reservoir pump is still 1.5 bar, do you think I should still check this pump?
