ThosL Posted December 4, 2023 Share Posted December 4, 2023 (edited) Could a remedy just be keeping the gas cap loose? Edited to add: I'm using a non-Subaru gas cap which may be the issue. I tried loosening the cap, no difference. Edited December 7, 2023 by ThosL Link to comment Share on other sites More sharing options...
montana tom Posted December 8, 2023 Share Posted December 8, 2023 You are not giving us any information. I assume your having trouble filling the tank? If so, your Evap system has issues and must be evaluated. What codes is it throwing? Link to comment Share on other sites More sharing options...
ThosL Posted December 11, 2023 Author Share Posted December 11, 2023 (edited) Hi--I cannot fill the gas intake except very slowly, when forced the gas overflows but most stations have pumps that do not permit that.

azdave Posted December 11, 2023 Share Posted December 11, 2023 I have a vehicle that for years would trip the overfill shutoff at the gas pump for unknown reasons. I found out that if I turn the filler handle upside down, I can pump at nearly full speed without tripping the shutoff. Not sure if that will work for you temporarily until you find out the issue. 1 Link to comment Share on other sites More sharing options...
ThosL Posted December 11, 2023 Author Share Posted December 11, 2023 I think it's something about the evap. canister, the code comes up. Cannot fill reasonably any way. Link to comment Share on other sites More sharing options...
ronemus Posted December 12, 2023 Share Posted December 12, 2023 It can be either the canister or the valve. It's easy to replace both and they're not very expensive, just messy because they're located behind the passenger-side rear tire underneath the car and road filth accumulates on them. 2 Link to comment Share on other sites More sharing options...
ThosL Posted December 12, 2023 Author Share Posted December 12, 2023 So I'll probably have to go to the junkyard. The pollution device in that area is also not working but since it does not affect performance have not devoted attention to it. Link to comment Share on other sites More sharing options...

ThosL Posted December 14, 2023 Author Share Posted December 14, 2023 The gas just spills out when I jigger the gas fill handle to pump out more, so not the shutoff. Link to comment Share on other sites More sharing options...
czny Posted December 14, 2023 Share Posted December 14, 2023 Have you checked the fuel vent pipe and hoses for kinks or dents. All this stuff is behind the passenger side wheel and metal shield. Could be rock/ice damage to fill neck vent tube. If the fuel tank can't vent it won't fill. 1 Link to comment Share on other sites More sharing options...
ThosL Posted December 19, 2023 Author Share Posted December 19, 2023 I don't drive on dirt roads where the fuel vent pipe would get crimped, etc.. Only in last six months have I had this problem. I tried to eyeball the critical area, hard to get access. Link to comment Share on other sites More sharing options...
