94 Z28 with badly blistered and about to rupture Heater hose between T and WP. I bought a 3 ft piece of Heater hose to run from that to the other point on the WP (completely bypassing the Heater Core. I live in AZ and use the heater absolutely never. Problem: there is a hose comming from the T that goes to a metal tube running along the fuel rail to the back of the engine. Does that have to be spliced in or can it be capped off? Need Help tonight! Thanks!

 

that line leads to the back of the heads. I would keep it circulating so the heads can flow. dont cap it.

 

Are you sure that the tee hose goes to the steam pipe and not to the throttle body? Have you done the throttle body bypass? You may need to configure your hoses like a 1995 or later to do what you want to do, bypassing the throttle body and getting a 1995 hose (large one )for the LH side of the radiator to water pump.

There are hose diagrams for the heater and radiator on my Tech Page.

 

Sorry,
last night it would not let me post a reply so I gave up. Shoebox, you are right I was looking at it wrong. I have not done the TB bypass but I am still going to bypass the heater core with a plain heater hose from the WP inlet to WP outlet. I went to the hardware store and bought a brass tee connector that has the right size for the main line and then a smaller diameter for the TB hose. Thank you for your help.
