Description

Boost Pipe Assembly for the 2.5L 300 TDi turbo diesel, part of the turbocharger boost control circuit.

It connects the inlet manifold to the injection pump’s boost control diaphragm, carrying turbocharger boost pressure so that fuelling is adjusted in proportion to manifold pressure. A sound, leak-free pipe is needed for correct boost-dependent fuelling; leakage causes under-fuelling and loss of power under load.
