That’s what I think too Penfold. In which case it may matter that the notch is facing the lip seal to prevent excess wear. Oddly I’d never noticed the notch before and don’t remember it ever being mentioned either but it may matter. It’s much easier replacing impellers than the lip seals. Thanks .

Thanks lustyd. I did insert the new one as you suggested but that does presuppose it was in correctly before Think there must be some reason for it

Sorry just Using an old one to photo. There is only a notch on one side. So issue is should it be in The way or out

Can anyone say what this notch on the impeller is for and should it be inside or outside when mounted

Many thanks to Paulrainbow and Geem. Problem now solved. As the pump was already mounted and the red wire between the pressure switch and the pump motor was under it in an awkward place I hadn’t seen it. As paul said by splicing into that wire and putting a wire from there to the bulb it now...

However even with an ordinary bulb I found if the light came on the pump didn’t and vice versa. Will try Paul rainbows solution and report back. The...

That just shows that you have power supplied to pump and will always Be on even if the pump isn’t running as it’s pressure switch has stopped it

Still trying to get a head and block for my md3b . The Pennsylvania one was wrong size.

Thanks for the info. Now have a block and head coming from Pensylvania I think. But once have that will feel more confident taking block off and maybe skimming it. I'm not a confident engineer ( yet) .

Thanks for replying. Its not really rusted through but more the head gasket has i think been leaking for a long time. Gas has scored the top of the block as the leak continued. Let me know if you remember the yard.

No longer needed.
