Pressure in gas tank

I seem to be building up lots of pressure in the gas tank now that some warmer weather is showing up. WHOOOOOSH! when I pull the cap off. I've been asking around about vented gas caps for these trucks but no one seems to carry or even heard of them. I think someone mentioned drilling a tiny hole in their cap, so pressure would be regulated a bit at a time. Any problems with that?

You can wish in one hand and crap in the other.
See which one gets filled first.
