It is essential that you choose the right injector or pump when replacing your faulty parts, not only might it physically not fit – but if you start the engine with the wrong part installed, you could cause catastrophic and irreversible damage to the engine. We have a fit guide which can help you narrow down your search to finding the perfect replacement part, however we would always advise that if you are unsure, check your existing fault injector/ pump for a part number and compare it to the list of exchange part numbers on the replacement unit.
