Franco, I've gone for a Samco boost kit and I intend to aeroquip everything else apart from the larger rad hoses. However, I have ordered a specific U-Bend through Mike Rainbird for the part you are on about.
For complete kits and service I would speak to Roose, You have to wait a while if you want something custom from Samco and I wanted my boost hoses black.
I would have gone Roose if I had known earlier that Paul Roose was a friend of a friend. I would have tried to blag discount then
