    I asked this on Garage,but didn't get answered.
    I have leaky pressure hoses from P/S pump to hydroboost,and from there to steering box.I was thinking to buy a new hoses,but they cost qiute much.So,I was thinking that get new hoses on a 1/3 of a price from hydraulic shop.
    Only problem is that I need fittings to connect the hoses.
    Well,I can get those fittings,but what is the thread size on pump,steering box and on the hydroboost?

    Where are your hoses leaking? Mine were leaking at the pump because someone overtightened the fittings and crushed the o-ring seals /forums/images/graemlins/angryfire.gif. If yours are leaking at the fittings, try replacing your o-rings first. I bit the bullet when I bought my CUCV in '95 and bought new hoses from the dealer. It wasn't cheap /forums/images/graemlins/eek.gif, even back then.

    Actually it is really pretty easy to cut all your existing fittings from the stock lines and solder them to compresion fittings that would attach to the new hydrolic hose. I did this myself. I'll try and get you some pics of my job.

    Both pressure hoses leak where the rubber hose connects to steel pipe.
    I also need another tank for the pump.I welded short lenght of a pipe on the tank for hydroboost return line,but I screwed up the weld,and now it leaks also.Should've soldered it instead of welding.Oh well,guess I have to take the whole system apart and fix it once and for all.
