Gas Cap Issues (RideTech)

[FloydSR]

I've got a 68 Camaro and recently purchased the RideTech gas cap kit. My question is do I need to vent it?

[FloydSR]

I've got a standard tank with a 350 SBC.
Would appreciate any advice…

Yes, that is non vented cap.

I have that cap on my 67. I drilled an additional hole for a vent that goes to the top of the Rick's tank. The other vent goes to atmosphere down by the end of the leaf spring. Never a smell in the garage.
