Charcoal canister in this year?

I would *think* if this came with a canister, the lines would be--

3/8 feed
3/8 or 5/16 return
?3/8 ? to canister
?/? tank vent if no canister

Holley Red states regulator not required.
Blue states regulator required.
Agreed with above-- Set pressure, & use a return if you go Blue - the pump can eventually over heat "dead heading" against itself & cause drive ability // delivery problems similar to if not including vapor lock.
Read the info on each pump you like. Ask Tech questions specific to your app.
