i have a spare fuel pump, i bought it for my series 1 rs before i sold it and never fitted it, its a standard cossie fuel pump, its not brand new but works fine because i have had it fitted to my dads rs 500 when his fuel pump went just to make sure it was the fuel pump that had gone and it worked fine, it has been sitting in my garage for a few months, yours for £25 + p&p.
