Took the pump to a garage/machine place this morning and sadly the sheered off bolt has wrecked the threads inside the pump
So have just ordered a new pump & bolts etc for the time being which should hopefully arrive on Tuesday, then hopefully have the car back running again.
Then sort it out properly at a later date when I get the chance, simply just need my car running normally again for wednesday until August time.
A big thanks to everyone that has commented/helped.
I will update you again once I hopefully get it sorted, cheers.
