Mine are dried & need replacing. Want to get the hoses before removal tho.

Anybody know the size?

Thanks

 

I believe they are6mm rubber vac lines.What i did just to make sure was go into advanced auto (or other) andtook the piece between my intake piping and the Boost controller solenoid located on the side of your intake box for the correct size. I decided to do this because i noticed somewhat of some lag and the dry cracked problem as you have noticed also.I replaced all three lines (one from intake manifold to wastegate, 2-from turbo to controller, 3-from controller to intake) and all pressures are very nice now Hopethe best in your results!

 

Or what you could do is ask your Volvo dealership.

Also go to Stylin Motors Inc. and get one of their vaccum line kits for Volvo's.

 

IPD has a great kit. do88 is a great place as well.

These lines are actually pressure lines, and generally 5mm. So it is recommended that they all get the correct size spring clamps of 7/16.
