Hi all,

An update to this - when pulling apart the mechanical fuel pump (again) i found one of the o rings had been eaten away by the fuel - hence the loss of fuel pressure. That o ring was less than 6 months old!

Anyway - o ring replaced and the engine is now singing again. I'll stick with the mechanical pump for now.

Cheers
Dave

Thanks Julian,

I can see where the confusion is happening - (apart from the manual!)- my cylinders are stamped as follows:

4.    5
2.    3
6.    1

Fan

Cheers
Dave
    Confusion yes. Mine are stamped as Dave's. Is this method of head numbering to match the distributor cap numbering, whereas Julian's numbering is assending numerically from the fan pulley rearwards? Also Museo Motori states 1 4 3 6 5 2 as firing order. Would anyone here be able to post a schematic ht lead diagram perhaps in plan view of what works correctly . My  distributor numbers match my head stampings at present. Richard

So some heads are stamped to match distributor cap numbers and some are stamped to match cylinder numbers. Back to electric fuel pumps, despite some instructions saying horizontal mounting is ok, outlet at the top is logical to allow vapour to escape, so I have remounted my Facet pump vertically/ outlet at top as a precaution against previous suspected fuel starvation.
