Fix, gas pump clicking off early, spider webs clogging vent tube
If you have a hard time filling your 2011 and up explorer because the gas pump keeps clicking off early or cannot fill the tank past 3/4. You may have been invaded by Yellow Sac Spiders, they will build a nest or web inside the evap vent tube that allows air to escape the gas tank when fueling. If this tube is clogged air cannot escape and the pump will think the tank is full and click off. This is a very easy fix, and have been told by a tech that it is happening very often with many types of cars on the road now.
first locate the evap cannister.
this is under the passenger side rear door
this is the vent tube coming out of the canister
pull the hose out and try to blow through this tube, it is just a vent. If you cannot blow through this easy it is clogged and is your problem.
this is the other end of the hose above the rear suspension. it is just held into the frame with a grommet.
pull out the grommet and you will find the diffuser end, make sure this is clear of spiders and webs, i am trying to find a sock product to install over this to prevent this from happening again.
now with this end removed blow through the pipe again untill you can blow without a problem, can also use an air compressor to remove the blockage. reinstall the pipes and the grommet and go get gas to test your fix!
