Fluid check valve, roll over valve
 

Any idea what the dealer will charge for a liquid check valve, and
roll-over valve? Are they still available for an 81 CJ-7? I've read
old posts and it sounded like people still thought they were available
from the dealer. I don't see them offered at 4wd.com

As I'm rebuilding my CJ-7 I figure I should probably re-incorporate
them into my fuel system. Thanks to the PO, the charcoal canister was
not hooked up, these weren't hooked up (broken and clogged with mud).
Any other ideas?
