Thank you Alan. That is really helpful. The cam must be above, not below, the aperture and I now understand the fitting instruction. My new plastic pump has a bent steel U channel type arm and I thought that what I could see through the hole was the blade below the big end cap which would fit into the U of the arm. Your wear witness mark has explained all. I’ll look upwards to find the cam and make sure that I tilt the pump upwards when I re-fit it.
Thanks again.

P.S. I wish that my tractor looked as good as the photo of yours but now with your help I can at least get mine back to work. 🙂

Thanks Alan. That is very helpful. I cannot see the cam through the small aperture that the pump fits into. I assume that it is out of sight below the aperture. If so I don’t understand the fitting instruction to ensure the pump lever is positioned above the camshaft. The new pump I have would not allow the lever to drop down that far out of sight. Is it likely that the driving cam could be so worn that it will no longer drive the pump?

Thanks Charlie. I already have the manuals but sadly the info on the fuel pump is limited and no good diagrams that I can find.
Thanks also David. I am with you on this issue. The old girl should outlive me if it is properly maintained. I still have my first car on the road which I bought in 1964 and that is now 94 years old. My last two modern cars had to be “thrown away” despite being in good mechanical order and both looked pretty much brand new but they both had minor electronic issues which could not be solved! My newest car is now 24 years old and precedes the era of electronics controlling the car but the electronics just advise. Even with that the other day my dashboard lit up saying “stop the car” because of low oil pressure. There was absolutely nothing wrong apart from a faulty electronic sensor.
Still hoping someone might recognise my fuel pump.

Thanks urbanalfa. I know the new pump works out of the engine which is how I identified that it was plumbed in the wrong way round but I am not sure if the blade on the underside of the big end cap is reaching the drive arm and unless I take the engine out and take the sump off I can’t see. That is why I hope someone who knows the engine might be able to identify if my new pump is the right one. I have asked the company if I can have my old pump back but I fear it might have been junked already.
