Power steering hoses
Thanks,
Dave
When I added a Type II pump to the BBC in my '75 with stock PS my solution was:
- Reservoir mounted between master cylinder and alternator.
- Feed line to pump.
- Stock line from PS valve to ram.
- Extended return line from valve to reservoir using a brass joining fitting and some 3/8" hose.
- Since my type 2 pump uses O-ring not flare to seal pressure side, two step solution:
1) Get metal line from NAPA that had O ring male end (pump) and O ring female. About 12" long and needed minor bending.
2) Replace stock '75 pump to control valve line (flared ends) with stock '82 line (flared at valve, O-ring at pump)
Been working great for 8 years and if I ever need replacement parts, it is all stock or hard line.

Dave,
I will see what I can do for pics. It is basically stock underneath. Biggest change is extension to return line to reservoir and then the hardline off the pump. I can't remember which hardline it is but it is male O ring to female O ring. I had a bend at the male end and then I had to make some small adjustments with a tubing bender to get it all lined up. Basically, it brings the pump outlet around the back to where the stock pump outlet would be.
Went out to the garage and here is all the info. Now, I did not want braided lines, but you could make them work using the appropriate adapters.
Tank is a Canton Racing 77-250. Has a 3/8 NPT inlet for return line and 1/2" NPT feed at bottom. I used brass 90 barbed hose fittings. 3/8" return line extended using 3/8" brass barbed union. 5/8" feed line from tank to pump.
Pressure hoses were a NAPA NPS 71729 (stock 80-82) hose and NAPA NPS 73418 which is a short 16 mm male O-ring to 16 mm female O-ring.
Here are some pics of the setup plus pages from older NAPA catalog showing the hoses (older style part numbers). Link to the metal hose:

Tank and fittings came from Summit Racing.
Pressure line (73418) at pump. Can barely see clamp for feed line from reservoir.
Pressure line showing bends to bring it around and behind pump.
Pressure line and feed line from reservoir.
Reservoir. Return line going into upper part of tank. Can just see hose clamp for feed line at bottom.
Hoses from tank going under #1 header. Hard to see but feed line is between return line and spark plug wire visually. About 1/2" clearance between hoses and headers on big block.
All stock at control valve and ram.
Best view I could get under car. Relocated oil pressure sender blocks quite a bit. Line with two hose clamps from upper left is return line from control valve. Pressure line is right above it and hooks to the hard line coming off the pump. Feed line is just below that visually and comes down from tank and then back to pump.
Better view of the connection between the stock 80-82 pressure line and hard line.

Hardline used to connect stock line to pump.

I have a Steeroids Power Rack and Pinion Steering system and it works well with the type 2 pump and the reservoir like I used. I made all the -AN lines myself and was able to get it working very easily and cheaply.
Use as big a reservoir as you can, because it will drop the power steering fluid temperature by increasing the volume of psf. Lower PSF temperatures will make the seals and other parts last a lot longer. On my C4 like many the Power Rack and pinions never last that long and mostly due to hot power steering fluid. The reservoir on the 1988 C4 is made of plastic and doesn't conduct heat very well.
On the hoses that I made I went and put an insulating cover over them to protect them from the heat up in the area near the pump.
The Best of Corvette for Corvette Enthusiasts
You should give Corvette Paramedics a call in Mt Holly, NJ. Maybe an hour from you.
Family owned, good people, great techs, great communication and fair prices.
Corvette service is all they do, usually ~30 cars there, saw a '54 and a '24 next to each other last week. That was cool.
As long as you do not have a 6 Qt oil pan, that some of the solid lifter cars might have, 340HP?.
Then it gets a little more involved, but still doable.
Beautiful car you have there sir!
