I may have goofed. I think I ran out of fuel in my Ford 1900 - there is still some fuel in the tank, but not much and it is on a side hill. It acted like it was going to start and then just kept turning over without a cough.
Anyway, think I need to bleed the fuel lines. I have all three manuals, but I just moved and they are packed away I know not where... Hope someone here can give me a quick lesson in bleeding the fuel lines.
There is one screw on the top of the fuel filter, so I figure that's the bleed screw. However, on the injector pump, there are a couple of screws and a bolt. Are any of those for bleeding? I figure one must be, but I don't want to loosen anything that screws up the pump.
Do I then need to loosen one or more of the lines to the injectors, or will bleeding the filter and the pump suffice? I am assuming that the filter and the pump should do it.

There are two bleed screws on the filter bowl of my 1710 and one on the injector pump. The procedure is to open both screws on the filter until no more bubble come out, close the screws and then do the same for the pump.
Unfortunately, the bleed screw on my pump is on the side of the pump and does look like something to adjust. I can't say what the bleed port on a 1900 pump looks like. I have used a banjo bolt where the fuel line connects to the pump for bleeding. It's probably not as good as the pump port, but there's also less chance of mistaking what it is.
Bleeding the fuel lines may have to be repeated a fair number of times to completely purge the lines. Typically the engine will run for a few seconds at low rpm and then stop. If the engine isn't catching at all, then maybe the pump does require bleeding or maybe air got through to the injector lines.
Injector lines should follow procedures in a manual, because there are safety issues. The basic idea is that fittings are loosened one at the injector end and the engine is cranked until fuel flows from the fitting. There is a lot of spray, working around rotating fans, belts etc., and there may be 2000 lbs. pressure in an injector line--enough to penetrate skin or put out an eye. Care must be taken when loosening injector line fittings.
I haven't had to bleed my injector lines but I hear it's a mess and each injector may have to be bled several times. Unfortunately injector lines often require bleeding after a tractor runs out of fuel.

Well Zero is not Zero any more and I ran out of fuel in my diesel pickup yesterday. We bled to the filter, but could not get the fuel to the injector block. Normally you have to bleed the injector lines and this is a 2 hour proceedure, at the dealer.
We decided to tow the truck up to the barn and have the tractor mechanic look at it. We towed it down the road and decided to jump start it, after towing some distance with nothing the system primed and we started the truck. Not the recommended method of priming but a lot cheaper. ....

OK, thanks for the help. I managed to stop by the dealer and looked at the diagram. Bleed screw on the injection pump is in the middle, the one at the bottom drains the oil from pump, the one at the top is to refill the oil in the pump. Just bleeding at the screw on the fuel filter and the pump wasn't enough, however, I finally had to loosen the "banjos" on the fuel filter and the pump to get all the air out and get it started. I will be sure to keep some reserve in the fuel tank at all times from here on... ....
