out of interest does a bosch pump run any quieter than a lucas?
i heard once that a lot of diesel engine noise is actually due to its fuel pump!!
as for the pump exactly, not as such, the bosch injectors (which fit along with the bosch pump) allow a greater pressure of fuel through, don't quote me on figures though... im unsure, but bosch>lucas all day...
XUD9s and Mechanical injection cannot *adjust* the injection pressure on the fly, the injectors open at a set pressure, you only adjust the injection *length*
