SNIPETTY SNIP Which sounds a very satisfactory arrangement in practice as reported, but I don't understand how the pump (sucking) deals with the air in the new filter with the bleed screws open or otherwise. I have concluded that SMH sets it up "filter before pump" so the filter protects the lift pump as well as the engine. Adrian has a filter for the pump and 2 more for the engine. Also, I didn't bleed the individual injectors - just the (external) injector pump and the theory is that once that is primed it'll force the air through to the injectors themselves. Though even that is a bit of a mystery to me because the air in the tube between the pump and the injectors would be compressible.I think once some diesel gets through to the combustion chamber the rising revs soon clear out any remaining air. Now what about an aglomerator, that separates spurious water from the fuel doesn't it ? Where would fit in the great scheme of things. I don't seem to have one Beeky
