Fuel system questions

Hello all, I'm a newbie to Jeep CJ's and this forum. Just bought a Jeep CJ8 sight unseen and has a few more problems than the online ad disclosed. First problem is that is won't start, but I'll fix that. As I was messing with the fuel system I found this module back by the right hand taillight. I'm guessing part of the fuel vapor recovery system. Pretty bad shape, all rusted up with the hoses broken off. What is it and do I need it? Would that be part of my no start problem?

I don't know what's on the right side, but on the left side there is a vapor recovery item and a roll over valve. Hoses go from the gas tank and to the charcoal canister under the hood.

You're right, I was thinking left side and wrote right side. Can't seem to escape this early onset Alzheimers. Are those rollover check valves and liquid check valves critical to anything? Or should I just bypass the whole thing? It doesn't appear that either of those parts are readily available, so I'm guessing that anyone who is re-doing their Jeep CJ is just eliminating that stuff in the rebuild. My rollover check valve is crumbling and needs to be replaced or bypassed.

I got rid of all of mine when I upgraded to the Howell TBI. I think they were more for emissions than function. Not quite sure if they are needed but mine is working fine without them.

It will run fine without them. You can simply loop a piece of hose from one nipple on the tank to the other nipple.
But you will need to vent the tank.... a vented gas cap works.

It's best to have the recovery system hooked up to recover gas fumes, but for now your concern is to get it running.
