Changed fuel filter on 7045. Can someone advise on the basic bleeding process? I've tried what I thought was sensible so far...Stanadyne pump if there is an option or differences

I cant give you any specifics but here is what I do on all makes of diesels that I have had to bleed.

Open or remove the bleed screw or plug on the filter housing(s) and prime with the manual lever if equipped or open the housing and left them fill with gravity.
I then crack the injector line at the nozzle. I usually just pick the easiest ones to get to. Leave it open a bit and crank until you see fuel leaking then tighten. Normally I have to do 2 or three injectors to get them to pop off and run a bit.

BE CAREFUL, the fuel is under a lot of pressure and can injure you and shoot all kinds of places if opened up too much.

On a 7045, remove the small plug on bottom of pump (takes a 3/8 wrench). Pump hand primer until all air is out, replace plug and pump primer up tight. Should start unless you have already pumped air in lines, if so pump primer, spin engine over a few times and pump primer again. May have to do it a few times before it starts.      MACK

My only experience is with a Long but it should work with most any CAV pump. Crack the bleeder screw(s) on the pump and pump/crank until you get fuel out of them. This is where an electric pump is nice. Next I crack all 4 injectors and let the electric pump run until I start to get fuel in all 4. Then tighten the injectors and turn it over until it cranks. Might need a little help (ether) but it usually starts and runs good. I start mine at about 1/2 throttle. This way works for me.

Well, thanks. But this was on Friday, I've long since got it going. And actually, this procedure wouldn't quite cut it as it turns out.
