Ionstorm66 Posted September 29, 2020 Share Posted September 29, 2020 Wondering what this little device with two hoses is. It's on the driver's side where the fuel lines go into the cabin floor. It has two hard lines that run over to the fuel pump. Can't really tell where they are going as the car was so much under coat. Link to comment Share on other sites More sharing options...
Numbchux Posted September 29, 2020 Share Posted September 29, 2020 Nothing I recognize. Spring clamps suggest it's in the vent line. What vehicle is this? Link to comment Share on other sites More sharing options...

I've been having an issue where the tank will have a ton of pressure in it when I go to fuel up. Like its hard to loosen the cap, and takes 10+ seconds to vent. It also soaks my hand in gas as it vents. Link to comment Share on other sites More sharing options...
naru2 Posted October 1, 2020 Share Posted October 1, 2020 It should hold SOME pressure.Can`t find a spec,but,I think it should be under 2 psi. Might be worth checking that the line to the cannister is not blocked. Link to comment Share on other sites More sharing options...
Step-a-toe Posted October 2, 2020 Share Posted October 2, 2020 Ionstorm, any fuel smell in cabin or rear after driving? Link to comment Share on other sites More sharing options...
naru2 Posted October 6, 2020 Share Posted October 6, 2020 Found a spec. 2 way valve relieves pressure above 0.5 psi+/- 0.2psi. Link to comment Share on other sites More sharing options...
