300TD hydro suspension lines: LEAKY!!!

[cscmc1]

Can anyone clarify whether or not the metal lines for the self leveling suspension in my 84 300TD should have a break in them just under the pass side front door? Both lines on my car have a plastic section of tubing held in place with small hose clamps, and one line leaks like a sieve. I have tried replacing it with a couple of different types of hose, but nothing will hold tight enough. The "splice" is at the block (with rubber insert) that holds the lines up against the undercarriage.

Any ideas? What is the working rpessure of the hydro pump? Any chance silicon on the ends of the metal tubing might help, or should I just look at brazing some copper tubing in place here?


Many thanks!
