Yeah didnt end up using the Vl turbo pump. Once i got the car on the hoist and had a good look around it became too hard so i lashed out and got a bosch motorsport 040 pump for it. Didnt realise how cheap those pumps are (at least cheap for me cos we are bosch dealers at my work WOO HOO).
Made a massive difference to the power output of the car now its not dropping pressure anymore. I would highly recommend them. Was pretty easy to fit. only minor modification made to the mounting in the tank. Lovin it.
