[Supras] PS reservoir lines?

[Walker, Brian (Rich. Dist)]

Does anyone know the technical name of the lager line from the PS fluid
reservoir? I've checked on the parts catalog and it lists the 'return
line' which I suspected would be the larger dia. line but instead was
the smaller line. They also list a 'high pressure line' but I was
assuming these went from the pump to the rack. I've had a small leak for
sometime where PS fluid will spray onto the area beneath the PS
reservoir, it appears to be coming from the larger line from the
reservoir (possibly near the connection as the hose is older and
brittle) Is there a single line from the reservoir to the pump? It
doesn't seem that it could be a high pressure line as it is held with a
spring clamp.

Thanks for any help,
Brian
