Anyone sell a power steering hose that is not so long?

There are a couple ways with your custom made hose.
If your fittings are regular inverted flare,straight or 90 degree fittings work great.
Go buy fittings,fit them to pump and box.measure amount of hose needed, have them show you where to measure on the fittings.
Cut hose, insert into fittings,then mark fitting to hose to index it. Return to store for final pressing of hose fittings.

3/8" two wire braid is stiff hose, it wont twist. If you can leave extra for engine movement thats better.
Flush the line with solvent and air before you install it.

Another type of fitting reuses your steel lines,utilizing a nut and ferrule, had one done on saturday. It works well, a collet inside nut crimps onto line and seals when you tighten it.
Weatherhead part number for the common 3/8" steel line is 06U-756.

Hydraulic hose can be cut with a hand grinder/cutoff wheel. So you could buy approx what you need and cut it as necessary. Still need to return to press it.

Pull hose and post up a good pic of the ends.
