would that be the roll over check valve? and i dont think i need it

It looks like the line to the charcoal canister no it's not necessary but you might get a dtc. Actually i don't thik you will because the 1g's don't have obd2 so you should be fine.

EDIT: You should put a filter on there like a little air filter, they sell them at autozone.

Sorry for the OTness but what is dtc?

check engine light. aka Diagnostic Trouble Code

I think mine actually has a little filter right there. No problems with it so, that sounds like the best idea.
