Quick Fix For Fuel Leak?

Have a fuel leak at the tank valve on a early 2000. It appears to be coming from around the shut-off thumb screw. Is there an o-ring or something in there that can be replaced easily? We"re already loaded up to head for the show this weekend and don"t really have time to pull the sheet metal and the tank right now.
 
You can either replace the valve or remove it and rework it so that the O ring can be replaced.

There is no way to repair the leak without removing or replacing the valve.

The good news: The valve can be R & R'd without removing the hood or tank. It will likely take you an hour or more the first time you do it but a couple of years from now when you need to do so again it will be a snap.

You did not say gas or diesel.
But if diesel here is a cool trick I saw used by the fuel company in a warehouse I worked in when I was a kid.
This trucking warehouse had 3 275 gallon heating oil tanks connected by 1" black pipe along the bottom filled with diesel. One day while loading freight I clipped that pipe and snapped it off right at the elbow coming out of the tank.
Diesel starts pouring out like a garden hose running. 1st tank had a vent on it and then the other 2 were vented by pipe to first tank.
My coworker quickly stuck his finger in the elbow to stop the flow. LOL. He sat there like that for about 20 minutes when the fuel tech comes.
He took off the vent cap and placed the hose off his shop vac on it and turned it on. Told Joe you can take your finger out now. Sure enough that vac had enough vacuum the open pipe just gulped air. He then just went ahead and repaired.
Now If we could get a tight fit on the diesel tanks on our tractors we could repair these annual leaking shut off valves without even draining the tank.
