Default Looking for 89 heater hoses

I'm looking for an outlet heater hose for my 89. This is the hose that goes from the heater core to the water pump and is 3/4" ID. There is no oil cooler, but it has a tee fitting in the back that goes to the intake manifold.
Does anybody know where I can get a new one of these? Chevrolet stopped supplying them in May of 99, and all the catalogs I have only list the inlet hose.

It looks as though the replacement for this molded, reinforced hose
with the 'T-fitting' may be a DIY item now.

Gates and Delco both list p/n's for a 2 pc 3/4" heater hose that
appears to be cut to length from bulk stock. 11" on one side,
22" on the other side of a 'TEE'.

I don't know what you get if you order the p/n's - a couple of
lengths of straight hose and a tee fitting? Here is an image
of the info from RockAuto

I'm going to lurk here too. Mine is cut and re-connected in about six different places I remember seeing one for sale OEM somewhere, but i think it was around $100

Incidently, if you haven't already sourced them, you might want
to track down the companion heater hose along with the upper
and lower rad hoses.

10108510 - Heater Core to Throttle Body
10135650 - Upper Rad Hose
10135651 - Lower Rad Hose

You don't have the oil cooler but for those who do, they would
want to locate the hose(s?) for it. I only remember having one
beside the oil pan but this doesn't make sense.

Check your Yellow Pages for an ACDelco vendor, I was able to
source hoses from them when the Chev dealer said he no longer
could offer them.

I cropped the prices to conserve space.

The Gates #28412 prices out at $0.67 ea (lots of 50).

The ACDelco #30125 prices out at $47.79.

My best guess is that maybe the Gates p/n is for the TEE and
the Delco is for a kit consisting of a TEE and a couple of pcs
of hose?

Checked, but www.acdelco.com offers even less insight.

Thanks for the info.
Looks like we're SOL on this hose, although all the others are offered by the aftermarket vendors.
I had an easier time getting the hoses for my 75 with A/C. Those both had to be molded hoses because the tubes on the heater core were pointing straight down at the pavement. I guess the C4's are in a zone where they're still too new to get more complete reproduction parts.

Call Chris at Superior. I emailed him a few months ago about the same hose. I think it was about eighty bucks.

Did you complete a purchase?

If so, any chance that you still have the receipt and if so, could
you look up the p/n? I am wondering whether it was a GM/Delco
item or one from another supplier. Continental makes some funky
molded hoses for my BMW's.

Actually, you'd still be able to read the information from the lettering
on the hose if all else is gone.

Thanks,
Ken R.

Lots of work, but to get rid of the bypass, swap out the intake gaskets for the F Body's which don't use the rear restrictors (or the bypass). Then stopup the manifold hole with a pipe plug.
