Following recent discussions re oil pumps, and that comment that the original pumps might be better quality than replacement when rebuilding the engine;



I have mine on the table at the moment. I know that my engine has been rebuilt before as the pistons are +20.
Can anybody tell me if this is the original pump from the markings?
What an incredibly simple piece of engineering!

 

mine looks different, it has a connecting tube and flanges where it bolts to the block.

 

Hobourn Eaton pumps were OE on a vast number of XK engines, 3.4, 3.8 & 4.2. XK150, E Type, Mk2, S Type, MkX, 420 & XJ6. Whether yours has been changed at some time we will never know. One needs to orientate oneself as to where you are viewing it from. It's the correct pump.
