Slow gas tank fill problem fixed! I had created a problem by adding on a large Gates filler neck to the factory metal tube. Fuel would pile up and trip the fuel filler handle. Would take 20 minutes to fill up the tank. I bought and installed some 1-1/4" clear fuel cell filler hose for $22. Although it was smaller, the hose also slipped right over the 1-1/2" end at the filler cap assembly. Note that the hose clamps are not in place in the photos. They are now. Can now fill-up the truck full speed.
Looking up towards the wheel tub mounted filler cap assembly.
