Hi Andy A recon pump for these is around £600.00. The charge needs to be this because if the diesel shop has the correct bench and add-ons for VP pumps then he has invested around £35000.00 in add-ons to a bench that would have cost him around £40000.00 originally. Diesel shops charge the correct amount to cover their investment, just like we should to cover diagnostic equipment. I agree with you though, a price quote should not change.
