do you know what other vehicles might be the same or if it has to be exact for your purposes?
might 2010+ legacy's be similar enough?
I just don't know. The PZEV could make it different/unique. I did get to converse a little with a tech about the issue of 'spiders' or something causing pressure to buildup in the canister - preventing easy refueling. He had seen 2 Foresters with re-fueling problems and he said one was definitely spider-'stuff- he had to blow out. Evidently some cars have a valve on the Drain-side, some have a little box with a paper filter? maybe both? , I will probably be able to find most of the components if I can get the car into my garage - just don't want to miss anything.
I've even considered just locating the drain line from thew canister and disconnecting it from any Drain valve, and building a screen-wire cylinder to attach the end, then just poke/secure that up outta the way. let the spiders and the ECU have a dead drain valve and some hoses/filters for their amusement.
The problem , I THINK (it's just a theory) is, the dealership is 17 miles away and if the ECU runs a Purge before the car gets there, the pressure would be relived in the canister, That's why it never fails for the service writers over there. This last time, I took video immediately after we picked up the car of my BIL unable to fill the tank without it continually shutting off. Dropped the car back at the dealership - they say they need the Regional guy. probably want to make sure mother Sooby will pay them for 'exploratory surgery'.
But, I can GUARANTEE you, this will happen again if there is ANY opening into which these spiders can crawl. The only way to fix this is, a perforated surface like a cylinder of screen-material on the end of w'ever hose or nipple or cylindrical boss is the final atmospheric opening. Once, they told my 85 year-old MIL that she needed to spray bug spray under her car regularly! that is BS.
