What a *&&^% complicated system. I suppose thats progress. Oh for those days where you had a rubber diaphragm or bulb to squash to prime the system, as in the 218 with xud peugeot engine !
It looks as though the design was given to a student with orders make it as complex and to use as many funny bits as possible.
Why the need for a saddle tank anyway ? For the V8 propshaft ? If so why not make a special tank for that , instead of a special for everything else ?
And how about a small pipe from one side to the other , outside at a low level ?
But also , full marks to you guys trying to understand how it all works . Thanks.
