Although the pumps appear the same, their setup is quite different so cannot be used on this engine. Their supplier had misidentified and supplied the incorrect pump.
With different part numbers, this could have been picked up on supply, but sometimes there is over-reliance on suppliers. Any differences should be picked up and questioned.
Now the cause has been identified, we’ve supplied the correct pump on order and will be attending site to replace it shortly.
