fuel pump

  1. All about MPG
    Hello. I had a fuel pump going bad in my 2.2 07 Cobalt. This caused problems, but my combined mileage was about 27-30 per gallon. I got a new fuel pump. My engine has more power, but my combined mileage dropped to 24-27. Is this normal?

    STRONG gas smell coming from rear of car prompted me to look underneath. There is a very fast stream of gas coming from front (engine side) of tank. Is this the fuel pump gone bad, clogged fuel filter or a possible broken/cracked gas line?

    I recently took my 2007 ls in for a fuel pump recall. It got to the point where it would hardly start and I could smell gas bad. I got it fixed and it has been starting fine.
