Power Steering LS to C10 Steering Gear

[TA_C10]

Hello everyone. I bought a stock type power steering gear for our 67-72 C10's to replace my manual steering gear. I planned to use the stock power steering pump that came with my 2003 LS engine. I figured I could just use NPT to AN adapters and run AN line between the two.

Then I found this adapter that reduces the flow. Do we have to reduce the flow from the LS pump to the steering gear or can I just run the pump with regular stock pump pressure/flow?

You dont need the pressure reducer, those are generally for rack and pinions.

I'd try it as is......but if it's a problem here another thread on a fix.....

Go to the local wrecking yard and fin a truck with power steering and at the one inch nut off the back of the pump, and take the spring vavle and nut and swap them on the the ls pump this will lett you use the stock 71 hose to the ls pump thats what i did and fsteering feels good

Wanted to come back and update this post. This is what I ended up doing.

From the beginning I had the idea fuel line, trans lines, and power steering would all be AN fittings and stainless steel hose. Everything went without a hitch until the return line from power steering. They don't make a braided rubber hose that will just slip on to the return line(I had -6 leftover and that didn't fit, neither did the ptfe). I already ordered the PFTE hose long enough to cover both feed and return. But the return line on pump is barbed with 3/8" in size and the pfte was much smaller and wouldn't slip on. In the middle of this I bought a hose clamp that looked like a AN fitting. So none of this was going to work.

Fast forward and I finally realized that the power steering pump return hard line was 3/8", so I ended up buying a 3/8" hard line to AN -6 fitting! Boom.

It just took a little extra work but I like how it turned out. If I ever have to replace the pump, I will modify it before installation and it will be an easy task. Of course I already installed my pump and returned the rental pulley puller/installer so I just did this on the truck.

Here is what I did:

The assembly. Hard line to AN -6 fitting. 90 degree ptfe fitting to fit my already purchased other end and hose I made. Otherwise you could use a cheaper/leftover rubber fuel or trans line with regular AN fittings.





Stuffed the line with piece of shop towel and cut the barb off the end with my body saw.






Chopped.







Deburred the line and sanded the paint off so the crush sleeve would slid on.







Made sure the crush sleeve fit and removed the towel with any shaving on top. Worked like a charm.





Fitting installed.





Here is final product. Power Steering done.

Nice fix...odd but I've never had a issue using -6 on 3/8" tube...fits pretty good...I've only done it on non pressurized lines though, but I've not had any problems..

yea, I was thinking the same thing -6 is literally 3/8 line. Used the cloth braided AN line for breather and PCV lines on my brother 440 New Yorker. OP the hard line adapter and AN lines came out great!

On your steering gear, are there o-rings under the -6AN adapter fittings? Or not needed with those adapters?

Not needed, inverted flares that seat in the gear.
