Bosch HP Diesel Fuel Pump Detail of Internal Workings Filter
I have tried searching for more detailed information on overhauling this pump. The MGR documentation does not go into enough detail for me. Does anyone have more details including information on a possible built in filter?

I wouldn't expect a built in filter, as there's already a very fine filter in the supply, just before it gets to the HP pump. Also it would be non serviceable.
Don't know this for a fact, of course. |

Do you mean by very fine filter, the large replacable element next to the battery box, or is there another filter after this one in the fuel line prior to reaching the HP pump? |

I thought there was a microfilter between the regulator and the HP pump? This is described on RoverRons site under the common engine faults section for the 75.

Its supposed to be at the HP pump inlet or in the regulator orifice area. Been a few folk looking for this elusive little blighter, but so far nothing. From what I have understood it almost solid sintered? and it would not take much to block it up with contaminants if it passed the LP fuel filter. |
