  well done, but how the hell you didn't get any crap in that pump I'll never know, would of been inclined to off cap off the inlets and outlets first and clean the outside of the pump

  hi I am fixing a pump like this. how did you remove the plastic pipe on the side of the pump? I tried pulling it out but I wasn't able because I was afraid to broke the plastic pipe.

  Can you go into more detail about flushing the pump through with diesel at the end. Which pipes do i leave off. Or do you connect them all but leave it unattached frm the engine?

  Is it not a concern that scraping that stuff off will get some of it in the pump?

  Too late to ask ,still you were mentioning about low pick up at hills as the symptom earlier have you checked the fuel pressure using obd tester,just want to know I am facing similar pick up loss at 2nd and 3rd gear,fluctuating rpm often,and during morning start when trying to move engine gets off after that its fine.But OBD tool shows 295 to 303 bar of fuel rail pressure during idling.bosch specification of cp1 pump is between 150-1350 bar

  Please clean the pump from the outside first and then dismantle not to see dirt on the sides (thank you)

  I keep hearing that these pumps through metal when they start going bad. Where does this metal come from ans what do you do to fix this?

  Should be wearing latex gloves and keep all precision components 'wet' with diesel…

  Hi, one question, once you have the pump removed, how do you install it? do you need to callibrate it or something? or just put it in place and put the bolts. Thanks you

  @7:04 This is the reason you should clean the entire outer body casing before commencing. Small micro particles that can be transferred is a no no. No particles ought be on the inside anyhow, so do take care its an awful lot of work to get it wrong. Good illustration video in both respects neg and pos = Perfect.

  Hi there! Great video Alan! Maybe you guys can help me with an issue. I replaced the seals on the Bosch CP1 cause I had a mayor diesel leak. After doing so, the engine fired up right away and I tested the car and everything seemed fine. The issue is that now, while I accelerate at full throttle, the car enters into LIMP mode and dies on me, you can turn the key off-on and the car will start immediately and I can resume driving… This didn't happened before. If someone knows what could be my issue or is there any part of the pump I should replace please let me know. Any help is much appreciated. Cheers!
