i have the borgeson catalog but didnt see the adapter for later fox pump
Don't rely on what's in the catalog, call them.
They don't list the fittings separately, but they include them in their hose kit, they *might* sell them. I ended up buying a hose kit, didn't like the hose routing so used just the fittings and made my own hard lines and hoses.
it is M16 but o-ring-- swivel..
Borgeson says the fitting needed for the box is 16mm inverted flare but what they supply has a sealing washer and seats against the box.
i cut a old PS hose today and used a -6 AN tube nut and sleeve and flared the steel line 37 degree so i can use -6 braided from there..
I assume you're using the right teflon stuff, the rubber -6 is not rated for that kind of pressure.
My pressure line is a rubber Parker-Hannifin hydraulic hose. Very durable stuff. I tend to try to avoid shiny stuff under the hood. I like to make things look OE if possible.
Borgeson told me the Fox pump should be fine for their box. That pump design was used in a bunch of different applications with, presumably, different flow and pressure settings, so it ought to be possible to find one that'd be a bolt-in that'd work in most any application. I've got one off a mid '90s F250 on the shelf, not sure what the ratings are on it, but it's the same configuration (except for the second return line fitting for the Hydroboost on the filler neck, which would be useful for a overflow catch-can in a track-car application.)
Of course, the big-block brackets that F250 pump came off of are being modified to adapt a late iron Delphi/Saginaw pump out of a Catera (Opel Omega MV6) for the ZF Servotronic box (also out of a Catera) that's going in the '64 wagon...
