The 85 westy project needs the lines replaced. Any thoughts/suggestions on using flexable copper pipe as a sutiable replacement.

..If you are referring to copper pipe used for water/plumbing etc... then the answer would be No..copper pipe does not have near the burst strength needed |

Paint is looking good...what's are the details on type of....gun......etc. ?
By the way, I don't think the copper lines are a good idea. They may be flexible but compared to a reinforced power steering line they WILL crack/split if you put enough repeated stress on them. I know this from the plumbing work I do in addition to the construction/handyman work I do.
Good luck

siphon cup,old emglo compresser set to 37psi, single stage "shop line" paint(pastel white) w/ water seperator. Nice day, low dewpoint,slight breeze. I'm just covering the primer at this point so I don't have to get to fancy with the paint atmosphere quite yet.
I just finished pressure washing out 20+ years of funk out of the carpets....nasty 
reefer line is as strong as type M copper.
How much pressure does the power pump exert anyway?

| On a retun line you might be ok. As far as the Pressure side of the system, It can have pressures over 500 psi. The earlier post is correct about a shop than recreate the hose/pipe assembly. Car Quest makes hoses for p/s. Powersterring hose is special unto itself. It is double lined and also does not deteriorate when oil touches it like a fuel hose or antifreeze hose. |

I'm assuming that you mean the lines front to rear complete? I think if it were me, I would hit the hydraulic shop and ask them which hard line they prefer for the job. Then see if you can buy the hard line from them, take it home and put whatever bends and whatnot in it and then return it to the shop to let them flare it to the proper profile with the appropriate fittings. Then have them make up the short flex line to connect the hard line to the rack. The stock VW flex line that goes from the hard line to the pump has a silencer built in it so you might want to get a factory replacment for that end.

| Bostig.com still may carry a complete exact fit, end to end hose for the vanagon |

If it was me(I work at a Mack/Volvo Truck dealership) I would make a nice neat 1/2" 2-wire hose up(I can't remember for sure but I think that size is good for 2000 psi) and fasten it underneath the van with loom clamps along the way, it would probably be over kill but would last a long time.
Just my two cents, my Westy has manual steering. |

| Copper plumbing line will likely burst the moment you start the motor. How much work do you think you can do at 70psi? PS operates upward of 600psi. With the transients you could see in such a small-volume system, I would get something with a burst strength of 1200psi, at least. |

A real bad idea.
Copper line will crack pretty quick.
Hit a Parker hydraulic hose shop.
Have some lines made outa steel reinforced hose.
It's the best answer.

OK copper is out. I had no idea the power pump had such balls, glad I didn't waste the time.
I do have a set of old AC lines  .............
Here is a thought___Pressure washer hose, 3000psi burst test and ok for solvent and VOC....... Comments?

| It's gotta be compatible with oil. Other wise it will get soft and POOF you got no P/S and oil everywhere. Are you just avoiding the inevitible chance that you are going to have to buy the correct hose? I understand but some things are just the way they are. |

High pressure paint sprayers are rated for oil based paints so I don't see the problem. I'm all about innovation rather then giving away $ when I can "tool up" for the same cost(or more if necessary). I'll share this in the forum as I progress.
My conflict is this is a V I'm going to sell and I don't want to use an untested mod on an unsuspecting buyer.
So I'll transfer my good ones from my 86 to the 85 and try the "paint hose" on my V

I was way low on my working pressure guess. It's three times as much with this system. The system pressure is supposed to test at 1668-1740psi (115-120 bar). See Bentley p.48.7.
So better make sure any materials you use are compatible with ATF (meaning oil and detergent), and have a burst strength far in excess of that pressure. 3000psi would be pretty good. |

| Then may I suggest that you sell it with a not working clause and quit trying to reinvent the already round wheel. Maybe the next guy will buy the correct hoses and be just fine knowing what is broken now. I am currently selling a VW. I tell them what is broken and let them decide. I had a nice girl needing a form of transportation and I found another car for her besides the one I have for sale. Fix it like it should be and don't try the "sawdust in trans Barny Fife" repair. No BS from me. |

what THF do you mean???????
I am the king of mods(converted my airV to I4 in 1993 so please pardon me if I tend to go off the reservation)(many of you were still watching Thomas the train or power rangers), the 85 gets MY "WV lines" and the mod goes to me on my V. I'm not reinventing the wheel, just attempting to find a way for ALL V owners to replace a existing issue with rusted power S lines and not get bent over by a shop. If I can find a way for ALL of us to repair this then my time is well spent.
Don't ever "Barny Fife" me again  Bro
If we were all to to the SA parts then is that also "Barny Fife"
Why not a easy to install 3000psi rated V owner friendly fix?
Sorry I'm venting:
The 85 WILL have the factory parts: my V is the test subject.

BF bought his Mom & Dad a new septic tank for their anniversary---
This going around the block to get next door with the Mayberry approach to just having some hydraulic hoses or steel lines made fits right into the BF frame of mind.
Custom made hydraulic lines from the pump to the rack would be the right way to go.
Not unless your just trying to jip the job to unload the toilet---
A better description than the BF job would have to be a Gomer or Goober quick fix---
