Copy this (ctrl+C):
Then open fceux, open the rom, open the hex editor. Then hit Ctrl+G, type 22C7, hit enter.
That should do it.
Don't forget to save, of course. And always work with backups so you can revert errors.
Just so you know it worked, open the debugger, and at the "seek to" field, type A2B7 and click the "seek to" button. The code should change to match the one I posted, minus the comments I added like "out of fuel" etc.
