Airnav does.

Enter your departure and arrival airports, then click on the tabs below to select 24 hour fuel, and another tab to see "Fuels prices reported within 90 days".
If you click on "I will create my own route" it will bring up all self serv stations within 20 miles of your flight line.
Play around with it and soon it will become your best friend for CC planning.
