Looking at the stock hard fuel lines in the Sprinter for the 4AC(feed, return and breather), they look pretty thin and pathetic, are these up to the job of supplying adequate fuel to a 4AGTE? Has anyone known of any problems with fuel supply reusing the stock lines?
I'll be running twin Bosch motorsport fuel pumps and an external surge tank to provide the fuel, it would be handy to be able to reuse the stock fuel lines which are already routed nice and neat.
