    Aluminum adapter fitting

    I needed a fitting for the '86 Chevy Power Steering return hose from the reservoir. The pump has a 3/4" tube nipple and I couldn't find a fitting to go from that to -10 37 degree flare. So I made one.
    Here is the pump with a long piece of 3/4id hose stuck on it.

    Inside this chunk of 1" diameter aluminum is a 3/4" OD "hose barb". You can't see it, but it's in there...

    I bought a couple of -10 weld bungs from Speedway. The bung will get welded to the barb after it's turned on the lathe.

    Continued in next post.

    The weld bung has an ID of about .47 so I drilled the barb out to .50 to make an unrestricted path for the PS fluid.

    Before parting off the "barb" I added a nice chamfer to the weld joint.

    I ran a 3/8th inch bolt thru the fitting to hold everything together for welding.

    After welding. I know it's not real pretty but it will do the job without leaking..

    Here is the hose and fitting held in place at the pump. Just imagine there is a piece of black hose connecting them together.

    I cut the piece of hose down to length and mocked up the fittings.

    With the return line attached.

    I really don't care for the naked hose clamps so I put on a couple of clamp covers I had in my stash.

    Sorry about that. Fotki is my picture site and they are in the process of moving servers so a lot of older pics are off line for a while. They are telling me they should be back up by the end of November...
