The power steering return line clamp at the pump is some sort of crimped band. Is there anyway to recreate this clamp including sources of the band? Or anyway to remove the current one for re-use? All replacement hose kits I've seen come with a worm style clamp.

Re: Recreate P/S Return Line Clamp
Donald,
I don't know of any way to reproduce the clamp you are talking about but I can tell you that it's the same part # as the clamp that holds the small radiator overflow hose that connects the radiator and expansion tank. If you look at swap meets I'm sure you will find some. Timothy Barbieri -

Re: Recreate P/S Return Line Clamp
Donald-----
The clamp that you mention was used for the power steering return line-to-pump attachment beginning with the 1970 model year, although some very early 1970 models may use a screw-type clamp. The clamp was a special design which required a special tool to install. Of course, the factory had such a tool, but I don't think you'll find these tools too common otherwise. These clamps are a one-time-only sort of thing. To remove them the clamp has to be pried off or cut which destroys the clamp. In SERVICE, a screw type clamp is used.
Curiously, the clamp, GM #5690839, was once available in SERVICE. However, it was discontinued in July, 1982. I don't know of a current source for it or, if you obtained one, how you would crimp it in an effective way.
A shop which specializes in making up hydraulic hoses for construction equipment, aviation, etc. applications might be able to help with both the clamp and installation, though. If so, you could just bring the pump and hose in to them for installation of a clamp.In Appreciation of John HinckleyComment

Re: Recreate P/S Return Line Clamp
If it is the clamp that is slightly oversize, and is crimped so that there is a small loop, and a larger loop going around the hose -- similar kinds of crimping are used on some constant velocity boots on front wheel drive cars. The crimping tool, which looks like a pliers with a single tooth on each jaw, is commonly available in the tool catalogs targeted at professional mechanics.
The real challenge would be to find the material for the clamp, as CV joints are much larger diameter.TerryComment

Re: Recreate P/S Return Line Clamp
I am not familiar with the clamp, but if it is as Terry describes, then it is a common item on vintage Mustangs and the clamps and the crimping tool are available through National Parts Depot and other mustang sources. If I recall the hoses are about one half inch diameter on the mustang. It would be worth checking into as Mustang parts are much less expensive than our corvette parts, and you should find the clamps easily doable from than standpoint!Comment

Yes! It is available, plus...
...the current offering is made slightly longer than the original to make it easier to install. Uses the the same tool as crimp style fuel hoses. Check with Glazier's Mustang Barn, I know for a fact they can supply this clamp.

Re: Recreate P/S Return Line Clamp
On my car, I carefully removed my original, and then re-crimped it on using the tool for CV joints as described by Terry (I used to be into VWs). It really does not HAVE to be ruined when you remove it if you're careful.

Here It Is...Finally...
Click on the Mustang, click on "View Online", click on "Fuel System", and advance Acrobat to bottom of page 84...shows proper clamp installation and pliers. Clamp is $5.95, pliers $24.95. Sorry, I couldn't get the link for the acrobat catalog...you'll have to click a few times.
Whew...Dave, I feel like I need a shower!
