I have a 9540. The fuel lines you are having problems with are some of the worst I've ever seen. My tractor has a little over 400 hours on it, is parked out of the sun, and they've ruptured several times. Kubota fuel line is outrageously expensive and that check valve you're talking about is $60 if I remember correctly. I learned the hard way a couple of weeks ago that the NAPA fuel line I substituted is not rated for diesel, as it broke down and blew off the same check valve. The engine will run all day blowing diesel out the fuel line at the rate of several gallons an hour, but shut down, reconnect (or replace) and she requires a prime to start. There's no fuel line blockage, the fuel filter and screen are fine. If there's a restriction, it may be in one of those check valves, but I can't see inside and I don't feel like spending $60 for $0.60 plastic parts. I had a biology problem that I eliminated with biocide and a few filters. Most of the dead biology ended up in the screen, but it took out the filter body and priming pump. The priming pump is not rebuildable like the screen. The replacement works for many applications and the first thing I noticed is the offending return line is optional. One of these days I'll get mad enough to think through Kubota's fuel line engineering and figure out if there's a better way to plumb the fuel return because that tangled mess of rubber lines is the worst thing about my 9540 after the fact that it only has half the ability of a MF or Ford tractor of equivalent hp. My advice is: repair the fuel line and purge the fuel system. If she starts, expect more trouble in the same place and keep going until the fuel line blows off again.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
