A Happy Ending:
I replaced all bar two seals in the pump - the one behind the weird triangular plug at the high pressure end and the one in the dump valve. The seal kit from Milner Offroad contained MOST seals, but I had to purchase three or four more.
I managed to get the pump back together OK* and "my man" re-fitted the pump plus changed the timing belt and idler at the same time. All is well again and I'm back on mineral diesel until the two-tank system is ordered & fitted.
Can anyone recommend a suitable two-tank kit? How about dieselveg.com?
*One important tip re: pump disassembly: when withdrawing the high pressure end (with injector outputs) from the main body, make sure the pump is vertical - i.e. 90 deg from it's normal orientation. This way, the numerous rollers, sleeves and washers won't fall into a heap inside. Not a problem if they do, but it took me a while to work out which end the dished washers fitted. Obviously, use the vertical orientation during re-assembly, too. BR, David.
