So i got the fuel lines fixed today and no leaks.

After i got the car home which is like 3 miles from the shop although i took a 10 min detour i checked my upper radiator hose and it was hot as hell and swollen and my lower was ice cold. I used a 50-50 mix and a bottle of water wetter. I've got a good feeling that its bled out properly cause i did it three times. But i was just curious if this is normal. Heat was blowing hot as well. And gauge said it wasnt over heating on way home.
Again this is a 92 240sx and it has a mishimoto rad and twin electric aluminum fan shroud. Thanks Josh
