1) Pic shows the (broken off) fuel pump seat/packing bit (bakerlite or similar) which, it seems, ages ago has broken off leaving part in the crankcase. Its obviously a slide it fitment, I think (and thats the first question!) but it wont slide out- help!

2)Pic shows exhaust gaskets for heads, but does it matter which way around they go? Shiney side towards head or what?

3) Pic shows a diagram of exhaust system for a DG 1900cc water cooled engine.....Ive marked two brackets A and B. These were NOT fitted to my system when I took it all apart.....should they be?

Thanks people.....
