After my initial hesitation about the new oilpump, I decided to further dig the subject. Surfing the web and reading lots of forum threads, one thing became clear: there are a lot of different pumps "out there". The engine in my car being a X-flow, you must know that there was the pre-xflow as well. Then there are the original Ford pumps, side-driven with or without angle. To add to the confusion, you can also find front-driven pumps, separate or integrated into the engine front cover. And to top it off, you can choose between dry sump and wet sump systems with according pumps.
Search criteria for me were 'side-driven' and 'wet sump'. I found three different pumps, but there might be more. A lot of small specialized companies developed and build their own. Since this engine has been on the market for several decades, there are a lot of different pumps both old and new.
Ford Burman Oil Pump (used, 50.-£ at Historic Racing)
Neil Bold Filter Type Pump (around 335.-£ + VAT at Historic Racing)
Pace DSP5 (around 250.-£ including VAT at Burton Power)
For the techies amongst you ...
... and finally, this one I really adore. The guys at Throbnozzle Racing apparently sent this to Pace to explain what kind of pump they imagined best for the Ford Kent X-flow.
Cheers.
