Looks like the fuel-ups imported ok, but I see some duplicates that you might need to remove.
The six fuel-ups you added were dated between 4/24/2008 and 5/24/2008. So you just need to view your entire fuel-up log and go to that point in time. You'll find a link that says "View All Fuel-ups" on your vehicle profile page. Click that, and you'll get
here. You'll see all of your latest fuel-ups there, and at the bottom of the page you can go back in time. As I write this you have four pages of fuel-ups, and to get back to 2008 fuel-ups you need to click on page 4,
here. Scroll to the bottom of the page and you'll see the fuel-ups you imported.
The important thing to keep in mind is that we show fuel-ups in the order of the date of the fuel-up, not the date it was added.
