Oops. I must have been day-dreaming earlier.

I found this pic on Autozone site in the repair guide I mentioned:

Thanks, Joe. Very helpful diagram. If I'm reading it correctly, it shows the canister screwed to the radiator support near the DS headlight with the PFS and CPS in the hoses connected to the canister.

Yea Bob, and I also noticed that base part number for the "Hose and Valve Assembly" in the pic (9C987) matches up with the part number(s) you posted earlier.

ok, got under there yesterday. There were some pretty bad dry rotten hoses. There were only a couple. I highlighted them below.......Some of the hose conections were ok and were not dry rotted. So now the next step would to be replace the two that are rotted?

That's what I would try first. If that doesn't fix it and no more leaks are found, I would replace the PFS/CPS assembly next.

The assembly is probably a dealer item. I would start with the 97 part number (F57Z-9C987-BA Canister Purge Solenoid/Flow Sensor) and ask the dealer to get you the equivalent part for a 96 4.0L.

This would be for the whole assembly correct?????? I was wondering where to get just the hoses from????? Unless What you stated was for the hoses?

Yes, it appeared that you were asking about the assembly.

You should be able to get hose by the foot in the correct diameter from an auto parts store. You'll want something that is fuel resistant because these hoses carry fuel vapor from the tank to the canister.

Welp. I replaced all the cracked hoses with new. The inside of the old hoses still looked good, but the outside was dry and cracking.........? But anyway, the light is still on. I put new hoses on friday and drove it all day sat, and today. So what is next? The canister?

I hate to bring this up but another leak could be either a bad gas cap or not tightened. I don't know how many times friends wives(& mine) didn't tighten caps down & I've came up with the same codes dealing with the evap. system. I just tighten the cap, reset light & 99.9% of the time its fine.

Yup, click it several times. My point is even if its tight the cap leaking(bad) could also throw a code. You can have the cap tested.

The trouble code for a loose cap or other major fuel vapor leak is P1455. The EVAP monitor attempts to pull a vacuum on the tank and then counts the time it takes to bleed up to a certain vacuum level. This vacuum level is measured by a pressure transducer in the tank. The size of a leak can be inferred from the bleed-up time. If the initial vacuum pull cannot be achieved, the P1455 is the result. This is called a gross leak failure of the evap system integrity test.

Your P1443 code is for a functional test of the purge system. When the PCM commands purge flow from the canister to the engine, it monitors the flow rate with the Purge Flow Sensor. A bad PFS or a leak in the purge system can cause the P1443.

The 2 codes are not related. The vent to the canister is shut off during the tank integrity test, effectively making the two parts of the evap system independent.

I still think the Purge Flow Sensor assembly is bad. I've already posted on it in this thread.
