whenever I go to fill up my gas tank at about 15 gallons it suddenly gushes out a bunch of gas. When I try to fill it up again it does the same thing, therefore I have to fill the tank super slowly instead of preventing this. Do you guys know how I can fix this issue? Is there pressure inside the tank that isn't being release? Thanks!!
The vent tube has probably been plugged with sediment, dirt, etc. One thing you could try is pour some sort of fuel cleaner (lucas,stp, whatever) into the fill tube to see if you can clear it out. To me thats the cheapest/easiest fix to try first.
