Re: Vented Gas Cap
Do you already have a gas cap on it? If so just drill a tiny hole in it and save yourself some money. Thats what I did and it works great! Much cheaper!

Re: Vented Gas Cap
I have to ask, on my 91 Z28, I have a seemingly common issue where pressure, or vacuum gets built up in the tank. Why is this... Is there a tank vent that gets clogged over time? GM wouldn't design the cars overlooking this would they?

All the fuel injected cars with the intank electric pumps gets pressure buildup, it's normal.
