Hi I have a 97 2-dr Blazer and I am wondering About the 3 lines connecting to the fuel pump, if the lines are pointing at you what are they left to right? I know there is a Gas line, return gas line and Fuel vapor line? If I am correct... So anyways which is which? Thanks!!!! The one on the far left is kinked and am wondering if this is causing my p0440?

 

there is 3 differ size lines. 3/8-biggest=fuel feed-5/16-mid size return,1/4-vapor-smallest. if the little one is messed up than that can deff be one of many probs causing a po 440

 

Yea last night I was just looking at everything, it looks like the vapor line is pinched, at a 90 degree angle, more kinked i guess, But I was looking at my charcoal cannister and all the lines and I realized the big 1" vapor hose inlet on the can was clogged not allowing air into it, so I looked in and saw a little filter type thing that seems to be holding in the activated charcoal I poked at it with a screwdriver and it was crusty but I kncked some stuff back to let air through so hopefully that fixes the CEL I turned it off so I am just waiting to see if it comes back on, if it does I will fix the bent line which should be fixed anyways,

Thanks for your help.... I may also have a leak!
