    This week the CEL came on of course just before I needed to take the truck for state inspection, I checked the codes & I have a PO455, large EVAP leak. Today I removed the battery & battery tray from my wife's 99 Sport (4.0 SOHC) to check the EVAP lines & replace the vapor canister purge valve/solenoid that is under the battery tray. The lines looked good but there was some stuff rattling around inside the old valve. I was able to pop the cap off & a couple pieces of black pellets came out. The metal line running to the rear of the truck to the charcoal canisters is rusted pretty badly so I am going to cut the metal line & replace it with a rubber line. When I cut through the metal line a whole bunch of little black pellets came out of the line. Here is a pic of what came out of the line. I am going to run a new line from the charcoal canisters up to the front & do away with the rusted out metal line.

    Looks like the charcoal from inside the evap canister. Guessing you'll be needing a new canister too.

    BTW - If you have a lot of rust the canister bracket is probably rusted away and the canister will be laying in your spare tire.

    It was rusted away, I found a plastic one on a 2000 Explorer in the JY & replaced the rusted metal one last year.

    What was left of the old metal canister bracket.

    I found it in a JY in a 2000 4 door Explorer. The next time I have the spare tire down I can get the part number off it.

    Update: One of the charcoal canisters was missing the little screen in one of the connector holes so the charcoal was getting into the lines. I replaced both of the canisters & the vapor canister purge valve/solenoid which was supposed to hold vacuum & was not. I drove the truck for 30 miles today & no CEL & 6 of the 7 readiness monitors are ready. We will drive it a couple more days then take it for the state inspection.

    Hm a question... What happens to the motor without it? Over here in Eu if you have a lpg converson you are not subject to emission control. I am doing a rebuild and a few days ago i removed whole instalation and it looked poor, rusted away. Prior to that, car run just fine.

    Update #-2: I have read it says to get the EVAP monitor to set & get the P1000 code to go away after repairing the EVAP system you have to drive the vehicle for 10 minutes between 45 & 65 MPH. I took the Sport to work with me & got on the highway & set the cruise control at 60 MPH & ran it for 10 - 11 minutes, then changed my speed until I got to work. I took the Sport to the state inspection station after work & it passed inspection.
