UIM to brake booster pipe part number

[Swanny_UK]

I'm missing the pipe between the UIM and the brake booster. I understand it's supposed to have a one way valve in there. Does anyone know the Mazda part number for a replacement, or a good alternative?

I had a badly perished/split one on my old car, I just replaced it with appropriate sized vac hose and a check valve from ebay.

Solved the issue with that car having 0 brakes yet basically all new hardware etc ..

I believe the OEM part number is F10043640B, it should also have a check valve in it so you need to fit it in the correct direction

I've just replaced mine with a new one from Amayama... just looked like a normal rubber pipe to me

It does deffo have a check valve in it, give it a squeeze in the middle lol

From memory I actually though the same and just put vac hose on, then wondered why I had 0 brake assitance after a pull (it keeps the vacuum in the booster)

Took a while for me to realise the obvious lol...
