Tractor Repair: brass fittings, ford 601 workmaster, fuel leaks

Question
I own a Ford 601 Workmaster diesel tractor. It has some serious fuel leaks coming from the brass fittings from the tank to the fuel filter,from fuel filter to the injector pump. I am disabled and only have one hand,so it makes it difficult to remove the fittings to check them out. Do you happen to know the size and what they are called, so that I might make an educated search for these fittings. Thank you in advance for any help with this problem. By the way, it is a 1961 with 2700 hours after rebuild. I am an intermediate mechanic. I'm sorry you've had so much difficulty with your volunteer effort. I personally applaud your efforts. This answer will be viewed as soon as you respond.  Gary
