Pump works! Luckily I didn't really move that lock nut and there was even some gunk on it that allowed me to reinstall it very, very close to where it was. I probably need to check the calibration but I know I'll be starting out very close to where I need to be.
Now I've gotta figure out how to hook up all the wires to try this thing out.

We have ignition!
For anyone else who wants to bench test one, here's how I hooked it up to the battery:
12v to:
Female connector with two red wires going to it.
Female connector with a black wire and a blue/white wire.
Ground to:
Recirculation fan ring terminal
Safety switch brown wire ring terminal
Brown with white stripe from timer switch
Ring terminal near coil with a brown wire and a red wire attached
I do have some troubleshooting to do.
After it runs for a few minutes, it seems that the safety switch wants to trip. I'm need to figure out what is causing that.
Also the combustion fan is a little buzzy. I've got two others but was having a hard time getting one of them apart. So I may swap to just see if any of the others work without opening it up. Or run this one for a while and work on the other later.

A couple other questions I'm hoping someone can help out with.
This would be going in my '73. So it has a metal heat tube from back to front. I'll have to cut that.
I just crawled under there, It appears that maybe the front part of the heat tube is not welded to the distribution box in the front, and only the back part is welded up. Is that correct?
If it is welded in the front: I do not know for sure if my distribution box is the same as the ones for a Bus originally equipped with a BA6. Would someone be able to measure for me from the back of the frame rail that the distribution box goes through, to the back end of the distribution box? That would tell me where to cut it in the front.
Similarly, from the front of the rear frame rail to the front edge of the flapper box?
Thanks!

Another thought/question, regarding the recirculation fan.
I'm somewhat hesitant to cut a hole in the body behind the back seat for the return, and I do not have the flapper box, so I'm thinking of other options or possibilities.
One is running the hose up above the transmission to minimize the dust and such it would pull in. This would still require me to come up with a flapper box some how. I have an idea using an aluminum exhaust vent for a dryer or something to kludge one together.
Another is not using the recirulation at all. Instead, I'd probably come up with two separate fans in the engine compartment to increase air flow there.
Thoughts on all this?

Holy smokes! Busy day in the thread.

One more question, sorry!
Does anyone have any pics showing where the heater mounts to the bus' body? |
My bus didn't originally come with a BA6 either so I cut the brackets off of the bus one of my units came from. I took measurements before I did the cutting though and here's what shows in my notes. FYI, you can probably fab your own brackets pretty easily.
These are by no means comprehensive, but should give you enough information to get close assuming these are sensible enough to a third party. Seeing these now, several months later, makes me realize I need to get a metric tape measure.

| Does anyone have a parts source for these? I am in need of a fuel pump and glow plug for the BA6 in my 78 Panel Bus. German Supply, who carries a fair amount of parts for Eberspacher gas heaters, is out of both. I have done some searching on thesamba, but have not lucked out as of now. Thanks in advance, and apologies for jumping into someone else's post! |

Is this a drawing of what the three brackets look like? Looks like they are/could be made out of 1/8 inch angle iron, with a slot cut in where the bolt for the rubber hangar bit to go through.
Am I interpreting that correctly?

Searched google images and found this one that gives me an idea for the front bracket, at least, and also a good illustration of where the heater needs to be placed.
From a different BA6 thread:

Does your heater have the rubber mounts attached?

They are mounted to the horizontal cross members. And yes, the slots are for the rubber mounts.

My combustion air blower is running (albeit still fused to the exchanger) but I have no pulsed ground to the fuel pump. I do have the constant 12V.
I want to believe it's something other than the points after reading

but it looks like a straight shot from the points to the pump for the pulsed ground, correct? |

Jason has a good video on testing your points:

I had to replace my combustion fan because my pulsing ground was weak even though I could see the points pulsing.

No pulse from the fuel pump points testing it directly at the connector. I have another combustion air blower that bench tests fine.
I'm still stuck getting the blower off the heat exchanger. Andrew how did you achive

Alas, I had to sacrifice the lip of the combustion fan housing (I had a spare). There was a white crud stuck in the seam between the combustion fan and the flange on the heat exchanger. I was a little impatient though, but I think with some penetrating oil and time and with some cautious prying around the sealing surface, you should be able to get it loose. When you reconnect the two, just make sure you apply some sort of anti-seize or other suitable substance to keep that from happening again.
I can't say for sure if you're going to need to pull the heater exchanger unit to separate the two, but it'll certainly improve access if you do.
