Simple window washer tubing question

Hi.

Not with the car at the moment but wishing to replace my window washer tubing as it looks brown and terrible does anyone know off the top of their head the inner diameter of the window washer tubing please? I'm guessing 4mm but just wanted to make sure

thank you

Should be 4mm, instead of running it up the rain drain, re-rout it with a nylon hard line hose in to the Grommet on the left side of it.

Thanks as always bri. What 3 hoses are they?

Well originally, they were 2 vacuum hoses and the washer hose.

I removed the Egg-Crate which eliminated the one hose with 2 large Chrysler check valves hiddened in the rain tray, I moved the washer hose and fed it with the hard nylon hose through the hose frame to make it cleaner and to clear the rain drain.



I used a brass barbed fitting to joint the hose at the firewall seal so it wouldn't get crushed and diminish the flow of fluid.

Here is how it is routed now.



Here is how it looked when I got it home the original


I hated working around those tubes.

mk3 golf in scrappy, lovely shiny black hose

The washer jet end was 4 inner
But the reservoir end was 5 inner

I bought 4 inner and found this out after I ran the hose as you said bri to the reservoir end 🙈

Just wudnt push on

Hold the end in some hot water to soften it .

Wow wish I'd thought of that before purchasing more pipe 🙈

LOL.... Live and learn mate !
