    I am putting a LS3 in my 1970.
    What are people doing for power steering hoses.
    I have a corvette front dress, with plastic resorvoir. The nipple seems to be just a around 3/8.
    I tried to use a -8 braided flex hose with teflon with a clamp, but cannot get enough crush on the braided hose to seal it to the nipple.
    Any ideas, or tell me what you have used for hoses.
    Thanks, Pat.

    I used -6an hoses on mine, a High pressure stainless and a low pressure stainless for the return. You just have to make sure to get the correct fittings for the style of hose

    I pushed the return hose on the nipple and used a standard hose clamp and a hose clamp cover to hide the clamp

    The high pressure hose is smaller in diameter

    Thanks, what is a hose clamp cover, do you have a picture of it and where do you get them form it.
    I have it sealed right now with a gear clamp. But do not like the look of it.
    The single Ear Clamp I had was not sized correctly and would not seal it up, not enough crush.

    It's just a decorative cover that slips over the gear drive clamp, I found it on eBay and wasn't a whole lot..maybe $5 or $6 shipped. I'm still using the worm drive clamp on mine too...this just hides it

    I have the GM front end accessory drive which is a C5 set up. The high pressure hose for a C5 corvette is $16. It is also the easiest one to work getting it to fit into the pump. I cut the end of the steering box side and flared it. Seems to work and is probably the cheapest option out there. Just cut the correct end of first, ask me how I know. For the low pressure side, used the original steel part off the steering box and extended the hose with a clamp.

    You can have custom a custom hose made for the pressure side with the correct ends. The return line I just cut the stock metal line and crimped a clamp on it

    Everyone says that but around here, no one would touch making a pressure hose and there are plenty of hydraulic stores for industry or agriculture. Probably a business opportunity I should explore!
    $16 for an OEM quality hose and free tool rental, done.

    I'm running the Corvette setup and I used the factory pressure line from my 73 with with an O-ring to flare adapter... Seems to work just fine..

    For the return, I usually cut the nipple off and install a compression fitting. If I recall correctly its a 3/8 to 6an compression fitting. Something like what this guy is doing:

    71CamaroGuy is right on the return hose. I have the same setup and used a -6 braided rubber hose with a worm-drive clamp and a decorative cover like he shows in the pictures. You can get them at nearly all of the retail parts stores or through Summit or Jegs. On the pressure side I had to remove the stock fitting and replace it with a fitting that has a -6 male fitting. Detroit Speed and Flaming River have them and Summit has several varieties. Real estate is very tight in there (very close to the pulley) so I used a short, straight fitting (AAF-ALL48210 from Summit) and a 90-degree AN tube fitting for PTFE pressure hose that allowed enough clearance to the pulley and the pump housing. Summit has a nice kit that has everything you need, including the AN fitting for the pump (SUM-G3160)--It can be used with the GM plastic reservoir mounted on top of the pump or with a remote reservoir (IIRC it includes extra -8 or -10 hose for the remote reservoir). I used the kit with the GM plastic pump and had to buy the decorative plastic clamp cover separately. Hope this helps. You're going to love the LS3!
