TR6 Windshield Washer tubing - size?

[Tri 250]

I pulled my heater assembly this past weekend to fix a coolant leak. While I have access, I thought I would replace my windshield washer tubing.

I believe there are two different sizes used:

1 size from the pump / reservoir to the tee

1 size from the tee to the jets

Does anyone know the Inside Diameter of these two lines?

So, after quite a bit of digging and some research, I’m using 1/8” ID from the tee to the jets. 3/16 ID is what I’m running from the reservoir / pump to the tee.

I'll be doing the same thing soon, Gary. Thanks for that research. Mine, like yours I assume, is yellow, almost brown. They work ok - seem to, and with that they are more brittle, may have better pressure control. I don't really care on that - just looking forward to cleaning it up.

If you get a moment, let us know how you pull and replace this. I am going to try to do this from just the engine bay with the hood up. My guess is you need to pull from the T side, away from the reservoir, and once run, then set up the T, and sprayers.

Also, where are you sourcing the tubing?

Cheers - thanks again for the post

Thanks Guv

I just got the tubing this week from Moss (sold by the foot). I searched the net, but I was playing with nickels and dimes so I just got it though a British parts source. They were the only ones that gave some insight to the size (that I could find) Some of the hardware stores carried one size, but not the other and with the price of gas I didn’t feel like running all over town. Since I have my heater and glovebox out, routing is pretty accessible and straightforward. However, I can see this as being a bit of a pain if at least the glovebox is not removed. The tee appears to only be accessible from inside the car and under the dash so I would think you would need access here to connect both sizes - reservoir to tee, and tee to jets. I also have my wood dash unscrewed and leaning forward for accessibility to the heater.

You nailed my reasoning for replacing - dirty, crusty, old and yellowed. It’s served it’s purpose after almost 50 years and was probably seldom used. While I had access, I decided to access. I’m not as limber as I use to be so I took the easy route. Not sure the older you get the wiser you get applies here because sometimes we have to do things 2-3 times on these cars before we get it right. However, I do feel the aches and pains more so the next day after twisting and turning my body to get to things in the car - especially under the dash.

On vacay so my project will be paused for the week, but I’ll post how this goes once I get back on it. I can’t remember how many feet I ordered of each size, but I’ll post this too once I get it routed.

Any pet shop with aquarium supplies will have the tubing, just take a section of each to match up.

Moss and The Roadster factory sells all the correct hose and connections. I bought mine for my restoration from "The Roadster Factory".
