They are not the old Lucas CAV rotodiesel pumps as used on the previous generation of Mondeos and Escorts. Saying that, I never ever had a problem when I had cars with that pump back in the day.

The Focus TDDI uses a Bosch VP pump which is fully electronically controlled. The said same pump that VAG used to use on their TDI's.

The fuel computer was plug and play on mine, all I needed to add was the stalk (indicator stalk with the button on the end to cycle through the fuel comp's functions) and an external temp sensor. I never bothered with the washer bottle sensor.

The only thing that is a bit squiffy on the TDDI is the range function. This is due to the TDDI having a 53 litre tank opposed to a 55 litre tank the petrols have. The MPG offset can be calibrated from the fuel comp and is very accurate once set up.
