Good eye and you are right! Ive noticed the line on my spares here - and that they are the hash mark for start and stop.
Ill take some pics later of just the switches I have.
But there you have a 1970 with a late plastic twist type switch. _________________

I'm posting these pictures to compare the '70 & '71 owners manuals with reference to the auxillary heater....the '70 obviously shows nothing, where the '71 does...
1970 US manual cover
1.70 print date
1970 dash
1971 dash - shows aux. heater, #23
'71 aux. heater reference
'71 aux. heater instructions
'71 print date

I was wondering if someone might be able to tell me what year and switch my bn4 would work with? It's the older style pump with the fuel regulator. The 5 digit number on there is 201370. Also if anyone is interested I have had success with rebuilding the older style pumps with a diaphragm made of Viton rubber. Same rubber used in O-rings.(I have some to spare for the price of postage)

Thanks for the quick reply and offer. I'm just back from my garage testing it again. I don't have a lot of money invested in this. I have been trying to get the plugs out without success.Just to see what they look like. I don't want to put to much torque on them for fear of breaking something. If that's the case I'll just run it with a basic on/off switch if I can ever figure which wire to run to. I'm testing with the thermo.duct work on and have been pulling this top terminal on the relay (A) to get the run on.Is this where the on off switch would go?

I'll have to go check the 70 panel to confirm the knob is the correct shape but here's another one of those pull style switches:
Looking at these two switches, the one on the bottom is mine,( 6.70). It turns clockwise, and lights up, as the timer starts. The straight white line (pointing up) in the switch extends past the green face acting as a dial for the timer.
The switch above mine doesn't have that extended line.
I believe that is a visual aid in determining pull vs. turn.... ? |
I just looked at my serial number that is stamped into the ID plate of my factory installed BN4, 6.70 production date. The number is 1236, not sure if this helps. I have the plastic housing on my switch ( not shown in my photos). |

I ended up buying a defroster switch . I guess going the cheaper route.For now. The six digit number I got 201370 was the 2nd. number down(Ausfuhrung). I was thinking the lower that 6 digit number the older the unit was. My 4 digit number (Fabrik-Nr)is 3580.The cable that looks like a choke cable that came with it is orginal I think. It has a german name on it and looks like yours.

Can someone remind me what size the hose is which runs from the fuel pump to the heater itself? Mine is evidently leaking between the heater pump and the heater.
My heater spins up (I hear the fan) and the fuel pump is ticking, but it seems like the pump is just fighting the losing battle there!
Thanks! _________________ Mike

Mike,
I pulled my leaking fuel line off, and searched the internet to find one. This is before I knew of the samba. I found one, but it was NOS. So basically it was old, and did not hold up. I wanted to use the factory correct hose. I tried to have one made with no luck. Is your bus fuel injected or carbureted? Mine is carbureted ; less fuel pressure. I ended up stripping the old braided hose off of the fittings, and hose clamped new f.i. hose on them. Part of the fitting gets tossed to make this work. Not sure what your fuel pressure is. If this seems feasable, you will be able to match your fittings, if they are like mine, to a quality fuel line sold by the foot.
I am assuming that you are referring to the short braided hose that looks like a hydraulic line that is on the back side of the heater in the engine compartment....?
*** I just noticed, after posting this that on your signature, it looks like you have a '77. Different beast, I'm guessing. ***
Maybe this will help someone with an early carbureted bay
Peace |

Mike,
Can you pull your fuel line, to check it's condition, and verify that it is the culprit of your leak? If you pull it you might as well replace it. If yours looks like the picture that you posted, should be fairly straight forward. Since you have fuel injection, does your system have a return fuel line as well?... Just curious.

No. The gas heater is entirely independent of the FI system. The fuel take off for the heater is between the tank outlet and the FI pump (so, on the low pressure side) the hose to the heater's independent momentary pump is fine. I can easily replace the hoses, but the one which is leaking is the hose from the momentry pump, to the top of the heater.
I'm hoping someone can tell me what size the hose is so I can purchase one and avoid extra down time on the bus.
To answer your question, yes, I can pull the line and check its condition. But I can see that it is leaking so it is the obvious starting point. But, the local parts store is limited on their fuel line offerings so knowing what size I need will allow me to either source it locally or order it online as to keep this from becoming a multi-day project, _________________ Mike

If I were to go buy one Id get a 7mm. That one in the pic looks like a big 3/8th one. They dont need to be that big. _________________

Yes, 5mm or possibly even smaller. I used vacuum advance or retard line from Germansupply on my last one, can't recall which size though, definitely smaller than regular fuel line. _________________ Rust NEVER sleeps and stock never goes out of style.

That link leads me to believe there are specific eberspacher lines?
I've never had them on my heater, so I'm going to assume it's fine to use something from the FLAPS?
Sounds like 5mm from pump to heater is the way to go? _________________ Mike

It's not under any pressure on the metering pump style heaters, so as long as it's fuel proof and fits the nipples well go for it. _________________ Rust NEVER sleeps and stock never goes out of style.

Is that hose long enough to cut off a little piece to take into the auto parts store, as a last resort ?.... |
