hey guys, just recently purchased my 1998 2wd ls blazer and had to replace the fuel pump and fuel filter.....i'm only getting about 11 mpg....now i dont know what it was before but the people i bought it from said it wasnt terrible on gas. Any ideas??

 

Is your truck throwing any codes? If your check engine light is on the O2 sensor might be bad. It is a sure fire way to ruin your MPGs. I'd scan your truck to see if there are any codes.
