Hi Mark,
Just a word of warning, the map sensor will fail where that is, it needs to be inverted, ie the connections for the multi plug and vac pipe MUST be facing straight down, the vac pipe also must have a drop in it, so the lowest point is lower than the sensor, to stop fuel vapours killing the diaphragm inside it.
I'll send emails today sometime, but feel free to pm and nudge me if I forget, as my memory is hopeless!!
