Most of that needs a clean but little more, I think you'll find most of them will clean fine (I find new lift pumps don't look quite right and prefer to fix original ones, kits are available but be careful as they're often not quite right). The air filter bowl could be a bit trickier but that you'll only find out when you fill it with oil. Probably will need replacing (these were made by AC and Burgess, Billy's one is an AC one, If Daisy's one looks quite different it will be a Burgess one, parts are not interchangeable, only the complete air filter and only for certain periods),

that and the fuel lines would be best found in a scrapy or other second hand source as new ones are not great. The tap filter does look a bit like the parts book illustration, looks much better there nice and complete with the mesh and valve. The part no. on the tap it the AC one, not the Ford one (quite curious to see if it's the same as Billy's one). Glad you got good looking coolant coming out, the block drain tap should't really be a problem to open, they're made of brass and should free up with a little persuation. If oil mixture has come out I think that's good, can you now turn over with the decompressor closed? I don't recommend mixing pipes as only one is actually the same (the filter to injector pump one), all the rest are different and not interchangeable. Don't replace the water pump seal until you see it leak, you might be surprised. To change the seal you'll need a puller and press to remove and refit the impeller, which has to end up at 0.030" from the pump body. I don't recommend new pump bodies as they're wrong and normally for later engines anyway. What's the matter with the dynamo? A similar check as the starter should do the job, there's also the regulator in the dash buit it's normally well shielded in there and survives quite well. If you're getting new fuel in the tank I strongly recommend you use the old fuel to help you clean the tank, (the bit behind the steering column it the worst both for dirt and access, and it's worse on the later tanks as the hole is twice the size to accomodate the wiring, tachometer cable and throttle shaft) it works quite well and keeps the inside on the stuff it was made for, then you can use that diesel on rusty bolts and so on. Even if the inside looks reasonable you should shift some dirt by doing this. The water in the fuel is not great but as long as it's not in the injector pump or engine oil you should be fine with a good clean.
You're getting there.
