Default '92 heater hose source

I thought I would find this in a search, but I didn't come up with it.

GM discontinued the '92 pre-formed heater hoses.
Does anyone know of any aftermarket companies that have them?

Default heater hoses source

I just ordered a set of heater hoses and all the other coolant hoses from GMparts4less for a 93 LT1. I thought the 92 and 93 LT1 were the same? I will try to PM you the adobe dwgs. Call John Armstrong at 800 633 4867 for help. The only part that was NLA was a plastic tee.

I ordered all of my replacement hoses (for my '93) locally at West Chevrolet. Got them at a good price too.

I just stopped in at my local Chevrolet dealer yesterday.

He printed out the page for '92 heater hoses and part numbers.
The parts number list is saying DISCONTINUED for most of them.
The only pre-formed hose for the '92 I can find is the short "U" shaped one from the heater to the expansion tank.

The '94 (don't know if '93 is like '92 or '94) heater hoses are available yet.
The '92 does not have a "T" fitting.

How recently did you actually receive the parts?

From the information I am finding, the '92 is alone in its heater hose (and water pump) configuration -- the '93 is like the '94.
So, if I am correct, the '93 and up hoses are still available from GM.
But, the '92 isn't.

Sorry I could not help. The 93 availability is likely not far behind.

On my 92, when I changed the heater hose I used the newer hoses and did the throttle body bypass at the same time.You have to change the water pump and top rad hose also.

Actually, that is exactly what I have been considering.
I have to get a newer style water pump.

I used the old style pump. I driled and tapped the housing and installed
a fitting in it for the hose

Ok, I am going to go with '96 hoses on my '92 -- just got them yesterday.

I have a '92 FSM, not a '96.
Does anyone have a '96 heater hose drawing from the FSM showing the brackets on the right front wheel-well and how to attach the heater hoses?
I'd like to make this look professional/original.
