I replaced my fuel pump a few months ago and quickly discovered that I start running out of gas when my fuel gauge falls below 1/4 tank. I have yet to actually run out of gas because I immediately get to a gas station, fill up, and it runs fine again. The gauge seems to function fine, and when I do fill the tank from the point at which it starts sputtering, I'm only able to put in about 8.5 gallons. This leads me to believe that for some reason the replacement pump I put in (from Advance Auto Parts) doesn't draw fuel from the bottom of the tank - that it only reaches about 3/4 the way to the bottom of the tank. Another potential cause that I've considered is an issue with the pump that moves fuel form one side of the tank to the other - though I no nothing about this part/process. Has anybody else had this issue? Or any ideas/suggestions? The car runs just fine, and the gauge seems to work accurately, I just have to fill up often because the effective capacity of the tank is about 8.5 gallons. I'd really like get this figured out right now while I have some extra time.
