OK,
I have found a supplier who assures me that they have the exact type of pump I need so, there is no need to alter the piping thank goodness. £27.23 plus £4.95 P &P
They deal in BMC & Thornycroft spares
They are only 20mins from where I am would you believe!
They only do mail order. I ordered it yesterday and it arrived today but I missed the post so I will pick up tomorrow.
Here's the supplier details for anyone else who is in a situation similar to me regards unusual pumps etc...

I believe my type of pump was used on the vehicle below:
The Hindustan Ambassador is a car manufactured by Hindustan Motors of India. It was in production from 1958 to 2014 with few improvements or changes and is based on the Morris Oxford III model, first made by the Morris Motors Limited at Cowley, Oxford in the United Kingdom from 1956 to 1959.
Despite its British origins, the Ambassador is considered as a definitive Indian car and is fondly called "The king of Indian roads".[1] The automobile is manufactured by Hindustan Motors at its Uttarpara plant[2] near Kolkata, West Bengal. Some Indian politicians, such as Sonia Gandhi, use the Hindustan Ambassador.[3]
As of 25 May 2014, the Hindustan Motors suspended the production of the Ambassador
