Will this vented gas cap fit my 96 z28? I deleted my evap system at the engine, and I need a vented cap now!!! I was looking for a keyed vented cap that would fit but im not finding anything.

I didn't even think of this. I know the shop took out the EVAP system (without telling me. Didn't realize I needed a vented cap. What's the downside of not having it?
Pressure build up in the gas tank. Loud hissing when opening gas cap. I imagine that can't be good on the fuel pump. I have been leaving my gas cap very slightly loose so pressure can equalize. I wonder if the shop capped off your vent tubes/charcoal canistet tubes when removing the evap system?
If it's a Stant, like mine, then I doubt it is vented.
Yeah, mine isn't either. I wish someone knew if these were the same size. Parts configurators will always say they're not compatible just because our OE is non-vented.
IIRC there were a few different generations of OBDII? LT1 had one of the first generations of OBDII and I don't think it was that sensitive. I remember reading a lot of complaints from LS owners getting a DTC after not tightening the gas cap enough. Not positive, but I think a GM gas cap is pretty universal for different makes/models.
