My 90 Pickup was originally petrol, but now has a 200Tdi conversion. Neither front wing has an intake to fit a snorkel, and I'd rather not source another wing. In the engine bay, the air intake is a large black cylinder with around 4" of round metal pipe sticking out and going nowhere at the moment, so I'm looking for a low-cost snorkel to fit to this. Has anyone found a low cost option?? Will I need to drill in the side of the wing, or is there a version I can drill the top of the wing? Do I just buy a tube to mount to the windscreen and fit a length of flexible pipe through the bodywork to the intake?
