Egil, I'd be interested to know what you're basing your conclusions about   
the Bosch pump on. I recently installed a Bosch pump to replace the Lucas   
unit. I've measured it putting out up to 155 psi, well above the 106-110   
needed for the Lucas injection, and I suggest probably better than the   
Lucas is capable of. I've been running with a pressure gauge connected to   
the metering unit for the past few weeks, and even under max load (4th   
gear, foot down, high revs up a long steep hill) haven't seen the needle   
waver below the 110 setting.
