Emissions Issues...ugh

[kernel.panik]

OK, so I have an 02 4wd tr4 with about 135k on her.

My former brother-in-law who was a toyota certified mechanic said that the 440, 442 & 446 codes I had been getting was the evap canister. Paid the $400+ for the dealership one about 2 years ago now and the CEL came back on a week later (comes on every other day in the winter, but not in the summer). Needless to say, I don't talk to him much any more.

Finally broke down and took it to the dealer for a proper diagnostic. They are telling me it's an "ORV Valve" and an "accordion" hose on top of the gas tank. I can't find those parts on camelback toyota's site to order, at least not under that description. (thanks to scrap metal [I think] for pointing out the toyota owner's website on another post where it listed what they told me)

My question is: how hard is it to remove the tank and get to these parts? I've wrenched on a few things here and there (replaced my worn out suspension), but never messed with a fuel tank.

Any help or tips would be more than appreciated. Dealer wants $520 to replace the parts, says it's all labor for pulling the tank.

Start by disconnecting the battery.

Drain the fuel out of the tank by removing the drain plug at the front of the tank with a wrench. Be sure you have a drain pan or bucket large enough to hold the contents of the tank. Run the fuel as low as possible before removing the tank from the truck.

Position a floor jack under the center of the fuel tank protector. Place a large piece of scrap wood between the jack and the tank protector. Raise the jack until the wood makes contact with the tank protector.

Remove the five mounting bolts from the ends of the tank protector with a socket and ratchet. Slowly lower the jack, allowing the tank and protector to descend with it. Stop when you have enough room to reach in and remove the connections on the tank before lowering it all the way. If you do not, you will break the wires or damage the fuel lines.

Disconnect the hose clamps at the base of the fuel filler hose and vent hose with a straight screwdriver. Pull the hoses off the fittings on the tank and move them out of the way.

Disconnect the wiring harness connector from the fuel pump on top of the tank by releasing the locking clip and separating the connector halves. Squeeze the two tabs together on the clamp that secures the fuel line coming from the fuel pump with a pair of pliers. Remove the clamp and pull the line free from the fitting on the tank.

Disconnect the wiring harness connector from the fuel level sending unit on the top, passenger’s side of the tank. Lower the tank all the way down and remove it from under your 4Runner.
