Max,
Which Westerbeke do you have they used W30, W40 and W50. The W50 is based on the BMC 1.8L Leyland diesel. Go to ASAP-supplies.com and search that motor.

My head gasket has gone twice, look at replacing the head bolts (studs). I made the mistake of not. They are harder to find, there's another source in England.

SW pump on mine W50 is a Jabsco pump #5320-0011. The FW pump is the same as a 1979 MGB. I bought mine for $39 with a lifetime warranty, at my local auto part store.
