Does anyone know anything about these? I have done the usual searches, but no luck finding a diagram or parts supplier. I am told it works, but a reco may be in order. Liquid-levers seems to not exist anymore.

It's just a variation on a Plumber's bucket pump. I made one last year, and they're really, really useful. Inexpensive as well.

I’m sure there’s one or two threads on here describing the conversion of a plumbers pump (like that one) into a hydro pump, including what fittings are needed and where to source them. Suggest you do a few searches.

Yes, done the searches and looked at all the posts re plumbers pumps. Its a pump/vacuum out of the UK, can be used for hydrogas (mgf) and hydrolastic cars. I have since found pdf operating instructions in german (have used google translate) and a couple of good articles on the net. This one, https://www.amvcnsw.com.au/austin1800/WS_Articles/MP_Hydrolastic.pdf lists it in the article. Somerfordmini have/had them for 620 pounds https://www.somerfordmini.co.uk/pump-hydrolastic-suspension-pumps-evacuates. I was just hoping someone had seen/used/serviced this one before. Thanks for the replies.

You might have better luck on a UK forum. There shouldn't be anything complicated to it though. Probably maximum three seals.

Too many minis

It's an interesting little unit; I did some searching and reading as well. I wonder if they use the underside of the bucket pump to pull a vacuum, as they look related. Do you think they were OEM for servicing 90s MGF? The company doesn't look to be doing very well; one director left, and there is not a lot of financial movement.

I wrongly thought this was just a plumbers pump. Realised now it’s an actual hydro pump. Apologies for the confusing reply.

I haven't found that out yet, but the unit is all over the MGF forums.
