Vacuum Tubing

[neill1607]

My tubes are looking a little cracked, so I was thinking about replacing them, but which size should I go for?

Samco list as Bore x Wall in mm

3 x 2

4 x 2

5 x 2.5

6.3 x 2.5

8 x 3

9 x 3

Anyone know the size

pretty sure they are 4mm

hmmm, although the manual states 1/8" (3.175mm) for some hoses.

The wastegate control line is 4mm. So is the fuel pressure regulator boost hose.

I just did all mine, I used 4mm internal diameter. The tube I bought was all black, so i just painted some coloured bands on each end to match the color codes of ones that came off. ( blue, red and white ) Of course these were just engine management vac lines, the heater controls use a smaller rigid pipe.
