The rubber hose that connects to the water pump cracked and needs to be replaced. I can’t seem to find this part anywhere. Has anyone had any luck? I’ve found some heater core hoses, but they are all rubber and don’t have a connection for the steam vent. The part number referenced is ideally what I want, but I am open to other options if someone has had to make this repair.

The heater core hoses are just bypassed at the moment, but I need to replace the hoses from the heater core to the water pump.

I have been looking myself, it appears we will have to make our own or find at them from a part out or junk yard.

Thank you for replying, it reminded me that I didn’t provide an update.
So, I couldn’t find the hose anywhere and it left me with a couple options. I could either remove all the hoses/pipes from the firewall to the water pump, or replace just the rubber hose at the water pump. I decided to cut the crimped connection off of the hard line. When cutting, I made sure to leave the last “ridge” of the hard line so a new rubber hose would fit on there and not slip off. I did this to both hoses as the other hose was not far behind from blowing out as well. Used a 8” piece of 5/8” heater hose for one line, and 3/4” for the other. Put hose clamps on each end and… voila! Looks factory, and only coat a few bucks for some hose and clamps. All fixed up!!!

If you could post photos that would be awesome.
I ordered this to try out.

What you bought should work just fine. I did not have a tee for the vent line, so this made me think of another option. In the end, I like the look of the “factory” lines, but I was ready to do the same thing as what you have purchased. I will try to get some pictures tonight. I knew I should have taken pictures along the way…

Ok, so here’s some pics for reference.
I started off by removing both lines from the water pump to the “quick connect” fitting. You have to make sure the yellow plastic piece is clear of debris or you won’t be able to get it off.

Then, I cut the rubber hose off of the hard line. You can use a band saw, sawzall, or a cutoff wheel if you’re brave enough.

Now, just add your hoses from the metal lines to the water pump. Here’s what those will look like when your done.
