Hello, I am new and I am looking for someone wise to advise me, namely the power steering pump that has failed me. I cannot afford a new one and I want to buy a used one. Can I follow the car model and engine power or do I need the pump number? I would like to add that the pump for electric-hydraulic power steering, auto Ford fiesta 2005, Mk6, diesel, 1.6 engine. I wanted to order from Allegro but there is so much there that I have doubts myself. I don't know if I can read the number from the old pump.
