I have been working on my 99 chevy tahoe for a while. I recently replaced the fuel pump with a new Airtex unit with a new wiring harnes. It doesn't seem like the float is working correctly. I have a 30 gallon tank in it but when it get down to about 10 to 12 gallons left in the tank my gauge will be into the red zone just about on E after only about 240 miles. I have been averaging between 12.5 and 13 miles to the gallon. Then when I fill it it only takes 19 to 20 gallons and the gauge stays on E for some time after it is filled. What could be wrong?
