I think I have the other Milodon pump, 10229 that is listed for the earlier, 65-67 289. I am still awaiting vendor info to confirm. The flange dimension is about right for the Tiger, so I hope it will fit OK.

An interesting point; the seller stated no backing plate is required. I have seen high flow pumps for sale in UK that use no backing plate so I really need to check this out for certain.

Your Milodon pump is listed for a wider application, for 65-69 289/351W so may not be right for the Tiger? I am guessing this may be why it was difficult to fit? Also, as it has a closed impeller (like mine) so I think there is some uncertainty whether if it is designed to be used with or without a backing plate? Again, just guessing really, looking for any explanations as to why it was so unsuitable.

Re your other pointsd, I did not know about the hose spring, so I will def check that out, thanks. I have an unknown Alu pump, which I presume is stock type, and no electric fans. I think your point about the rad core is probably the most likely explanation. I suspect it is original, if not just old, so a recored rad may be the answer.

If you do any more test runs, you may want to try the Milodon again without the backing plate, or try their other pump if you can get one. If I were more local, you would be welcome to borrow mine of course!

All the best.
