Ok, I got lazy the other day. The nearest diesel is about 15 miles from my house and I needed fuel for the tractor. I figured I had at least 30 gallons sitting in the truck so I decided to siphon some out. (I did this a number of times on my “Brand F” without any problems). As I pushed the siphon hose into the filer neck, it seemed to stop at a point. Thinking it was at a bend in the neck, I worked it around and it continued into the tank, but right as I got past the sticking point I heard a “clunk” in the tank that sounded like I had pushed a part of some sort into the tank. Is there a screen or something in the neck that I broke free? Anybody else have this happen or was it just my imagination?
