I am marinising an XUD9 and have bought a Jabsco raw water cooling pump which i wish to mount on the end of the cam shaft. The pump mounting flange and input dog is visible in the top left corner of photo 2271. Hopefully i can use the existing vacuum pump "base" as a mount for the water pump (with appropriate machining of the "base"). I was given most of the vacuum pump with the motor but i'm pretty sure i am missing some sort of plate that fits between the vacuum pump base and the end of the head. Photo 2271 below is what i refer to as the "base". In photo 2275 below you will see a gap between the vacuum pump base and the head. There is no reference/drawing or photo of this pump in the Xantia Haynes manual and I cant find one on the internet. Can anyone direct me to this missing item, or provide a part number, or let me know if you have one for sale please. Cheers Halsey
