Hi David, Yes, I see what you mean. Oh dear that burr is more than likely going to saw its way through the cam on the jackshaft. My first choice would be to send it back and get a replacement. 2nd choice would be a careful grind to remove the burr.
Hope you get a good result,
Tony. |

This version of the "early" fuel pump is shown in the diagrams in the early Dolomite 1850 workshop manual in sections 19.45.05 to 19.45.15. It then shows a picture of the "standard early" fuel pump. So I imagine it was also fitted to the Sprint as well.

| MY opinion - and it is just that - is that I wouldn't fit that pump on my car! Not only is the length different but the height of the end of the arm, relative to the pump body is also different, possibly by more than 4mm, it's difficult to tell! This could ... |

If the fuel pump pressure on the 1850 or Sprint is too high it can be adjusted down by fitting extra paper gaskets between the casting and the block, according to the manual. Not sure if its the same on the 1500 ??
