Here is the other one. http://www.subaruparts.com/diag/?mod...category=036-A

I have no idea what this does, as it is powered by 12 volts at all times and has no control signals whatsoever other than it shuts down when the fuel pump relay shuts down. I pulled mine off to check its operation using battery power. Seems to do nothing. I'm thinking about leaving it off the engine to see if it does anything, just bypassing it with a hose, as it always seems to be open. Maybe when it is hot it closes more? I'm confused too.
