Thanks for the heads up on Modernising your Mog DB, I can see the attraction in getting rid of the Lucas ECU with it`s early electronics, ageing quietly, and would present a real mystery for anyone still alive who might have what it takes to repair it should it fail, though it was a real step forward in it`s time but still requiring a degree of mechanical interface via the flapper and associated variable resistor...

Me.. ? I am happy to stick with carbs, slightly less so with Strombergs with their rubber diaphragm, and would have preferred SU`s without that issue and SU`s polish up nicer too...(-: My spares kit has a couple of diaphragms included, but I have only had one failure over the years..

The chap who rebuilt my +8, cut two pockets into the board covering the axle/battery, one pocket each side of the diff deep enough for some spares such as fuel pump dzzy cap and various other important bits and bobs, but like you DB, I have only required to use the parts mentioned earlier in the thread and only the tube on one Spanish trip and the fan belt in the French trip.... Just goes to show quite how reliable old Morgans can be...(-:
