in an attempt to source a possible boost leak ive decided to to replace as many of the hoses as i can, and check all other areas one by one.

i need to know the sizes of the boost hoses, the ones from the boost control solenoid, and any other boost related hoses.

(got a possible leak, that does it 3 out of 5 times halting boost driving me mad)

 

The smaller of the hoses you should use 3mm internal dia samco and the larger ones are 6mm internal diameter.
