Morris Minor Owners Club

Hi everyone from New Zealand.

I bought a 1958 Morrie from a lovely old man who lived 900 miles away. He had had the car stored in his garage for 30 years, but once the brakes were fixed he offered to drive it up to my city (what else but a morris could do a 900 mile trip at sitting at rest for 30 years

It made the first 700 miles, but then then the fuel pump diaphram ruptured. He put in a cheap electric one, and I bought a kit to recondition the original.

Now the problem is I didn't realise how tricky it is to get the diaphram in the right position and am having a very hard time getting it adjusted. I've tried doing according to the haynes manual (turn until the contact points don't cut over then turn back four holes). It does whirr away quite happily but doesn't seem to have enough suction to pull through the gas. I've tried adjusting it back but can't seem to make it work.

Anyone have any clues? I really want to use the original pump if at all possible. Thanks everyone.

Here is a video for an MG pump repair, essentially the minor one is the same.

Hope this helps and welcome

If you have followed the kit fitting to the letter, made sure the diaphragm is pulled back before tightening it all up I think then it should work well. I did mine last year and it worked a treat 1st time and continues to do so. It did seem to take while for the non return valves to seat, it would tick quite frequently with the ignition turned on and no engine running but has settled back to normal now.

Are you sure the there is no silt, muck or whatever in the fuel line from the tank, after sitting that long I would have expected the fuel system to need a good clean out. Can you blow down it.

The new pump may have a little bit more grunt in it to pull it through.
