1999 Ford Taurus. I have extremly low fuel economy (12 miles local, 18miles on highway). A car dealer told me it is due to the fuel pump. He said a good fuel pump stops drawing gas from tank at the fuel pressure "48", while the one of my car stops at "80". I never heard fuel pump would affect the fuel economy, is this explanation reasonable?
have the same problem?
