hey 6gc,
I have a question for your collective hive mind of wisdom. I'm trying to diagnose an evap emissions code and cant figure out what this wierd black box is behind my fuel tank. Haynes is useless since it doesn't even show it anywhere in the fuel system diagrams. I'm really stumped by this! here are the pics:  its located in the space between the fuel tank and the spare tire well  it has a bunch of what look like solenoids connected to it.  not only that it seems as though the fuel send and return lines are involved as well, but im not sure as i havent dropped the tankanyone know what this is? what it does? and how it can break/influence evap codes? --------------------  |

not uncommon for the evap valve on the canister to go bad since its the most exposed to the elements under the car there. usually you replace the canister with the valve because a common failure is for the charcoal to get loose and clog the valve or stick it open/closed. also they just fail where they don't open anymore but ohms test fine.
