My fuel pump is whining and I smell gas what do I need to do to fix?
Need to replace fuel pump and filter.
Do not drive the vehicle if you smell raw gasoline. Not until fixed. If you don't know where the leak is, you don't say what year, but regardless the odor of gasoline= risk of fire. for your Blazers sake second, and your very life first, do not drive the vehicle. Friendly advice. Try to find the leak.
