1999 silveado Gas tank filler tube vent hose conn location

[wdchparks]

I have a 1999 Chevy Silverado 6.0 Ltr C2500 Auto tran Large Gas tank 120,000 miles. My gas tank filler tube vent hose has come off of its attaching point. It is still connected to the filler tube. I can not see where it connects on the other end. The small hose is long enough to reach the rear bumper on my truck noticed it hanging over the differential on the ground. Does anyone know where to reconnect it to. I do have a check engine light showing. I fear my truck is falling apart slowly.

Thank you for any help!!!

It sounds like a evap line, check the top of fuel pump, see if any line missing. Also, some makes and models may have evap canister at the rear of vehicle. Check the canister at the rear, where applicable, to see if any lines are missing.

the fuel filler hose has the rear diff vent hose set into a plastic holder. this small 5/16 rubber line can fall off this plastic holder. it connects at the top of the hose near the gas cap behind the fender ...
