LT1 upper rad hose
I got my upper radiator hose(supposedly) from Zip products today. It is labeled upper radiator hose but is only about 8-9 inches long and about 1/2" in diameter. I'm guessing it's the throttle-body bypass tube. Anyways, is this common practice to call random tubes the upper radiator hose. I always thought it meant the hose going into the upper part of the radiator but I guess I'm wrong. Another great deal over the internet. Arrgggg. Any help here on getting a part number for the upper radiator hose for a 95-96 Vette? The one on the Zip site is not the correct one.

Here's the correct names from service manual:
Radiator Outlet hose - connects lower right (passenger) side of radiator to outlet of thermostat housing.
Throttle body hose (inlet) - connects from a T in the smaller diameter hose coming from the left side of radiator and goes to the throttle body.
Radiator Inlet hose - connects from the left side of radiator (drivers) to the T connection, see above.
Upper radiator host/throttle body hose connection - this is the T connection assembly.
Radiator Surge Tank Inlet hose - Off the surge tank (near passenger firewall) it looks like a J hose and connects to the upper heater core inlet.
Radiator Surge Tank Outlet hose - connects the lower outlet of the surge tank to the water pump (I think).
Heater Core Inlet/Throttle Body Coolant Outlet hose - connects lower heater core outlet to the throttle body.
there are two metal line ones:
Surge Tank Air Bleed and Overflow hose
Surge Tank Air Bleed and Overflow hose
Not sure how to distinguish these two, my guess since they have the same name is they come as a assembly pair, matter fact I believe I remember Chris at Superior telling me this once, they are kind of expensive.
If you want part numbers I have about 2/3's of them. I just have to go through invoices. I've replaced all except the metal ones.

When i bought mine they were refered to as upper front and upper rear, front is the one going to the radiator the rear is the one from the tee to motor. Got the pair at autozone for 24.00 (goodyear hoses)

You shoiuld have upper radiator hose front and lower radiator hose front.
Then you have the coolent tank hoses upper and lower.
And then the dreaded throttle body bypass hoses.
Some lt 1/4 motors have 2 front upper raidator hoses that go to the radiator and thermostat with a brass by pass for the throttle body .

Thanks, The island doesnt have it at all. All the parts stores and dealership dont have it. Strange. I will call my Dad and see if he can get it in Oregon and mail it out.
