The old tank is made of some kind of olefin plastic, but of course it pre-dates the introduction of material content labeling regulations so no markings to work from...

I tried for different epoxies to fix the cracks in the old tank. JB Weld Plastic Bonder seems to be the only one which will bond.

I also found a similar tank from US Plastic, part number 8819 if anyone else needs similar. It’s 5 US quarts, so around one imperial gallon. Less than the original, but unless you’re running a 1960s BMC dealership I doubt that will be a limitation.


Great stuff!

I will keep the US plastic tank in mind.
I have an Australian Austaloy pump which is the local copy of the Churchill. They have a soldered metal tank in place of the plastic tank. Mine was rusty as heck so I soldered all the holes and painted the inside with epoxy. I don't think it will last forever.

I've a mate who collects Churchill hydrolastic pumps :lol: I bought one of him on Monday and he went immediately to view another one he knew was for sale :lol:

I remember being told some years ago that when hydrolastic cars first appeared in 1962 only BMC dealerships had hydrolastic pumps, would that be correct?

For the custom seals on the pump pistons that are NLA, the originals will need to be reused. Classic motorcycle restorers rejuvenate rubber parts by a week's soaking in rubbing alcohol + wintergreen oil mix (3:1 ratio). I've never tried that but it's worth a shot.


I've had the seals soaking in that mixture for a couple of weeks, and the rubber definitely seems to have softened up and swelled a little. I am going to reassemble the piston at the weekend, and see if it will hold a vacuum.

I am sure that would have been the case. They weren't a cheap bit of kit either.
