I rencently replaced my fuel pump and it is making a loud buzzing noisy, as well as losing power once the fuel go's below a half a tank. Prior to replacing the fuel pump I never had any problems similar to what I am having now. What would cause this problem could it be a contaminated tank or is it from a faulty part?
