That would be your heater core lines. PN # 10236039 for your 94. I suggest if you havent already do the coolant bypass mod. I cant really tell by that pic if you have. Also you could do what i did and buy the 95-97 heater core lines that dont have that stupid nipple for the smaller coolant line that leads under the air elbow to the upper radiator hose. If you do that you will also need the 95-97 upper radiator hose. The part number for the 95-97 conversion is #10261147. I dont know the number for the 95-97 upper radiator hose but rockauto has them as well as gmpartsdirect.com just look at there catalogs.

so that line is a very large line that turns into a hard steal line?
