i think what eight is trying to say is "cooker ring lpg" = single point .
very basic system , and its way to old tech to run properly when installed in a p38a .
my present rangerover a 4.6 hse was fitted with single point when i bought it and to be honest it was a real pain , poor performance , regular blow backs in the air box ( i wondered why the previous owner had left the clamp loose on the air ducting ) , and poor mpg figures .
i put up with it for a couple of months and bought a sequential under bonnet kit at around £850.00 and installed it myself .
after i had done this the car was a totally different animal and 100% better drive .
you could end up spending 2 or 300 quid trying to get it to run ok and still be left with a totally unreliable and unsuitable lpg system .
gems and bosch are the engine management systems , gems up to 1999 and bosch after that date , the later bosch system is easily identified by the inlet manifold which is nicknamed banana type manifold for obvious reasons the earlier gems equipped engine has a rectangular shaped plenum chamber and says either 4.0 or 4.6 ltr on the top .
the cooker ring or single point systems use a mixer ring attatched to the end of the throttle housing to deliver the lpg to the engine where as , multipoint / sequential systems the lpg is controlled by a ecu specific to that system and it takes siganals from the engine management system to inject the correct amount of lpg at the correct time depending on the engines particular needs , multipoint as the name suggests , use`s electronically triggered injection to deliver the lpg to each indivdual cylinder .
