Just in case anybody wants to use veg oil in these things, DONT! The hydraulic head seizes and snaps off. Also if you live someplace mountainous, the govenor cuts the diesel (LUBRICANT!) going into the high pressure pump on overrun, or engine braking, the hydraulic head seizes and snaps off. When the pump gets bored, the hydraulic head siezes and snaps off. Makes me embarassed to be British.

Would that be for the DPC variety of pumps?
Aint got a clue smutts?!
What does DPC stand for?
I have not a clue, but it's the type that was used on lots of Citroens and Peugeots in the 1980's & 1990's. Ford as well.
But at a guess, Distributor Pump attempt C.
