I did half expect this type of reply, it’s a fair point, I do have a Bosch unit on my other car, but are we just paying for the name or something genuinely better?
I find it funny you saying "are we just paying for the name", how many of us when it comes to other parts for our Cosworths will only fit parts that are new or new old stock and must be genuine Ford, even though there are non genuine parts available at a fraction of the cost!!!
For me the Bosch 044 pump is a tried and tested item and I would not take a chance on something else because its cheaper and claims to be as good.
