Job done, easy but very time consuming but I wasn't in a rush, took me well over an hour just to remove the old gasket luckly I didn't have any broken bolts although the shaft of the three bolts that go into the block had surface rust, they were re-used but with a dab of copperslip on the shafts and thread lock/seal on the threads.
Pics show old and new pump, the inside of the old pump very clean for 14 years old and that gasket that I removed carefully with a blade first then with a bit of soft alloy strip as a scraper plus lots of thinners, shame the gasket didn't stay with the pump.
