What is the "Hydro Booster" (con't)

[okidok]

Thanks for the advice,

The inside of the booster is extremely clean (looks new in fact), so I'll check for sand grains or stuff I may have brought in.

As for the pressure accumulator, it goes for 165 € (here in France) and is sold 74 $ at pellican parts, the problem is that they will not ship because it is hazardous material

Ok, it would seem the leek has gone, hope it holds...

Tried AutoHausAZ.com?

They had mine for $83 and will ship.

I purchased one of Jay's kits. With a little patence I was able to rebuild the booster. Jay's pictures and words are spot on. He's also a great guy with fantastic service.
