I have a Case 450B that would not start. It had run well before but had been sitting for some time since running last. It would turn over but would not start, no smoke from stack. I had fuel at the filters and the pump. I cracked the injector lines at the injectors but had no fuel when cranking. I pulled the top cover off the pump to see if I had garbage inside but it was clean. After a lot of time involved the problem came down to being a section of rubber fuel line on the return side of the injectors to tank. The line had swelled up inside and wouldn't let fuel pass. This allowed pressure to build in the injector pump and stopped fuel to the injectors. Just wanted to put this out in case someone can use it.
