[V8] Hydraulic hose from Reservoir to PS pump

[bob moy]

So I decided to replace my leaking hose from the hydraulic reservoir to the 
PS pump.  I got the new hose yesterday and notice that the banjo ends have 
what appears to be o-rings.  I didn't get any new o-rings, so does anyone 
know what size these are or should I just try to match them at the local 
home depot?  The other alternative is to reuse the old o-rings presently on 
the car.

TIA
Bob
