EVAP Canister Lines (P0441)

[jimiburg]

Hey everyone, I'm currently dealing with a P0441 (Incorrect flow detected). Looks like the 2 hoses that went to the EVAP canister have disappeared in the last week or so. I can't find a solid diagram showing how to properly wires these back up. I've has issues filling the gas tank too. The pump keeps stopping every few seconds.

If anyone has photos of where these should go that would help me out. Looks like everything is still attached to the purge valve.

Thanks!

There should be a vacuum tubing and evaporative hose routing in the Factory Service Manual which you can download a PDF from in the TJ Resources section.

Looks like someone might have removed the lines that go to the Charcoal Canister from the tank and plugged them on the tank side, that would cause the EVAP code AND cause the gas pump to shut off while pumping since the tank also vents through the charcoal canister.

Or you could have the flapper valve problem in the filler tube.....
