I’m a newbie gradually restoring the rear end of my 1973 late bay project. When I cut out the rear offside corner there was what looked like micro-bore pipe leading into the engine compartment. Gas? Refrigeration? Can anyone tell me what is it please?
Hi Countryfox, a few weeks ago I wouldn’t have known from memory what they are, but with some reading of the Haynes manual and the threads in this forum, my knowledge is greatly improved. I’m quite handy but never worked on engines before but confidence is growing! Enjoy the van!
Keep the pipe ! If you chopped it, solder or braze a sleeve on it and reinstate it as you will need it to stop petrol smells later..
Best to get a manual (Haynes or Bentley) before you start chopping stuff out The vertical pipes and capsules are part of the (over-elaborate) tank breather system.
If the breathers didnt loop up with bulbs in them you could empty the tank by syphoning if you did the correct sequence of driving with the bus leaning one way then the other and stopping over at an angle , as the fuel level is above the tank breather inlet on a stock air cleaner. Or just brimming it. I expect a bus owned by the military did this on trials and they had to fix it...
