beemn 50 Report post Posted September 20, 2015 So i installed a secondary fuel pump into the e46. This is a fuel starvation kit which replaces the passenger side fuel sender. I had just on 3/4 of a tank when i installed it and they say the gauge can be inaccurate, when the new pump and sender went in the gauge was pretty spot on....jump to the end and long story short, when i disconnect the new pump and the old and turn my ignition on the gauge goes back up to 3/4...anyone have any idea why that would be???
