What would you do?

My May '71 FJ55 had an engine swap to a small block 350 by a previous owner. Recently I have been having trouble with a pressurized fuel tank, to the point of hearing the tank 'pop' while driving and fuel spraying out when removing the fuel fill cap. After inspecting many things, I think I've solved the problem with a new vented cap. (A vented cap was on the vehicle when I purchased it).

But... During my inspection, I found what looks like an attempt to eliminate the evaporative canisters mounted in the rear panels. I have the fuel tank with the four emission ports in the corners. All four ports are still connected to the two canisters. The outputs of the canisters are still plumbed to the hose and rigid tube running under the vehicle, but the two pieces of the tube are connected together with no output forward. No charcoal canister in the engine and nothing into the vacuum system.

1) I feel I have better things to do with my time than try and reconnect and make this system work again. Agree? Any reason to put this all back instead of a vented fill cap?

2) If this were your vehicle, would you leave the canisters in the rear or remove them and cap the lines?

Thanks for your input,

Jeff

Rebuilding the evap is a good thing. Even on a desmogged 2F it is one of the systems to keep. My suggestion is to replace all hoses, find a replacement charcoal canister, reconnect the outer control valve and ride fume free

in Arizona, a truck with vented gas cap will not pass emissions
 
Thank you. Not the easy answer, but I wouldn't have asked if I wasn't prepared to make it right.

That opens a couple more questions.

It's there anything to rebuild on the rear canisters? If so, is there a kit?

Does anyone have a picture of the routing of the lines forward. I'm sure the engine swap will require a different route, but having an idea where the original was would be helpful.

Thanks again!

Jeff
