Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
I'm working on the car over the weekend so I'll find the hose I took off and report back.
Fairly sure it's a single size, it's doesn't reduce. The replacement silicone hose was the same size both ends.
found the original from my car.. the metal side from the water tree is 26mm, like posted before.
The silicone hose on mine is only 24mm ID and it's fitted to the plastic filler end. So 24mm ID fits and works.
