New oil pumps for the M20 and other models are due for completion in approx. 1 week...These are UK manufactured pumps with a cast iron body which is both stronger and more durable than the mazac originals and will cure 'tight pump' problems...The pumps have the later pattern gears that improve output (as fitted to later Gold Stars etc.)...
If you are interested in one, or more, of these please contact me off forum by Friday next week at the latest.....Ian
Now as no one was making them in the past except for ABSF and they quoted £400 to get me one I now see Hepolite/Wassell also makes them. But it matters little as no one seems to actually have a Hepolite pump and more expensive than the one you will supply.
