Oh ya 87 GN...

should only be one hose if GN was converted to vac system.Most likely connected to vac block on doghouse.Which is a known area that leaks.Sounds more like bad booster or master cylinder.

Thanks Six,
I have no leaks on the master cylinder (should say no fluid Leaks)
I have good pedal feel at first but drops off rapidly..
Will go to the floor and i then need to pump.... No so much fun at 60MPH!
Any insight would help.. (Driving my Winter Beeter now)

Assuming (oh no) that you have the vaccum conversion...
The fact that your pedal goes to the floor and you aren't loosing fluid is a classic sign that you are loosing your mastercylinder. The fluid is bypassing the internal seals. Time to rebuild or replace.
