Has anyone fitted the later cast iron pump to their C25/B25/TR25?
The Rupert book makes clear the updating the oil pump to the later cast iron one is recommended - and details the areas where a bit of metal removal is required. The cast iron pump has three studs. I cannot find where the procedure for fitting a third stud is mentioned. Have I just missed it? Or maybe the intention is that the pump is simply secured by the two bottom studs? Or am I looking at the wrong pump?
Thanks
The third fixing is not used when fitted to earlier engines. It does work fine, I converted my (now long gone) Starfire following Ruperts most excellent book years back. This is the service sheet.
