Power steering hose fitting at Brazil Valve

[Cdog]

Anyone know what size this is so i can order a replacement? It’s the small one. The hose failed at the crimp and is seeping fluid.

Here's what I leaned recently, should have the info you need. (Not sure if my link to the post will work but here goes)

So just an update on this.

Seems there's no easy source of a fitting that goes from the new rams metric threads to the standard inverted flare to retain the original power steering lines. The closest I got was a fitting similar to the one shown in the original post (Weatherhead 1446 LS conversion fitting) that has the correct metric/flare threads but is about .125" too short. I could have just spot faced the new ram letting the fitting sit in deep enough but this wouldn't have helped me with the low pressure return side.

After a bunch of google research I finally decided to just make some fittings. I ended up making them with the metric "male" o-ring threads and 1/8 NPT on the female side since I didn't have a tool to get in and make the inverted flare profile. This way I just bought an 1/8" MNPT to inverted flare adapter fitting for both pressure and return sides. I wouldn't like to have a single fitting but oh well...gotta work with what ya got!!

Also, since the info isn't really out there on thread sizes I figured I'd add them here in case anybody searches about the same conversion in the future.

High pressure fitting:
Old ram 1/4" inverted flare (7/16-24)
New ram 14mm X 1.25 metric o-ring

Low pressure return:
Old ram 3/8" inverted flare (5/8-18)
New ram 16mm X 1.5 metric o-ring

A little time on the SL10 and here's where I got.

Threw them on the Bridgeport and put the hex on, then on the Logan manual for a quick touch up to the hex and all done.

Going to put it all together tomorrow and make sure it's all good!

This ram is a 1990 so it might be SAE. I might just buy the fittings if I can find them & run black nylon braided line.

Anyone know when the change to metric happened?

Yours are standard size fittings, uses 7/16 and 5/8 wrenches. The newer steering actuator with metric fittings is aluminum and looks different. Yours is based off a c3 corvette steering control valve and actuator.

Thx! That’s what I was thinking. Now to chase down the fitting.

That looks like the older saginaw valve, not the newer brazil valve

For the price of the merc replacement I’m thinking it would be cooler to make a line out of -10 black nylon braided line. Now I need to find the fittings.

Wonder if I can run a banjo fitting on the pump for clearance?

Just find a Hose - Man , bring them the hose and they will make one .

Take the hose off and take it to a hoseman shop they will make you a new hose using your original fittings

Ive had them make all kinds of hoses over the years with solid results and they are very reasonable the price.
