Is there enough room pinout-wise to add a feature to an MPGuino such as talked about here?

I know the code is near max size, but I think I can remove some stuff that I don't need/want for my specific application and write in what I would need to drive this. I'm thinking something along the lines of
When {fuel remaining in tank} <= {pick your minimum amount}
then set PIN X HIGH //turns on LED connected to PIN
else set PIN X LOW
I just don't have a full MPGuino built yet. I have my Arduino Duemilanove (the 2009 version, the Decimilia was 2008), but don't have the other stuff yet.
I want to include this in the enclosure if I can. My Lumina's gas guage on the dashboard is off by about 1/4 tank - very unreliable!
