Well to update everybody, it’s definitely a 2.5na engine with corresponding injector pump (fuel solenoid and timing belt cover probably should’ve been a clue for me )

Am I correct in thinking these are CAV DPS pumps and I need this kit?: https://injectionpumps.co.uk/product/lucas-dpc-throttle-shaft-kit/

Well, considering that you made that post twelve days ago, and nobody replied to your question, I'm assuming that you found the relevant information elsewhere.
I swapped out the old dog of a pump I fitted to my 2.5 (with timing chain conversion), for a pump which had been lying in a box for at least ten years.
To my amazement it worked perfectly, virtually no leakback, and a much better running engine.
Now, 1500 miles later, it's starting leaking from the input shaft.
There's play in the shaft, which probably explains the variable tickover speed.
I'm wondering if that £13 repair kit will actually solve the problem long term ?

The £13 kit above is to sort the throttle shaft, nothing to do with the input shaft.

When I had mine off I had the full kit [ the large O ring on body needed doing] I used their non genuine.
When removing top cover it is important to note which hole the little spring inside hooks to so goes back the same.
