Now you should be able to see several screws that mount the fill spout to the body, remove them.
Stuff a rag in the fill spout to keep dirt out.
Next slide under the truck bed.
Now loosen the clamp on the filler hose to fill spout connection.
Slide a small straight bit screwdriver under the hose to break it loose from the fill spout, be careful not to tear the hose.
When you get it loose, remove the fill spout.
The fill spout flange is inside the bed, so to remove it you need to bend the hose and pull the spout under the truck to remove it from the hose.
Again, watch you don't get dirt into the hose.
The vent hose should be clipped to the fill spout.
Pull the vent hose out of the fill hose, file 13 the vent hose.
Now put everything back together like it was.
Go fill the tank, check for leaks.
This does not get rid of all the foam problems, but it does cut down on them.
It also lets more fuel run down the filler hose, so fill time is reduced.
I sill like to use the smaller nozzle pumps when possible though, the big nozzle just flows to much fuel for a fill tube to handle.
Big trucks have a 3" or 4" fill hole right into the fuel tank, no tube involved.
