Brittle fuel hoses, leaking hollow screws and dried-out gaskets are typical wear points on the 2.7-liter B27F V6 in the 1978 260 models. When the smell of gas or damp joints appear under the hood, it is usually aged seals and pipes that need replacing.

This category gathers the parts that belong to the supply between the tank and injection on the B27F. The group includes fuel pipes and fuel hose, copper washers, O-rings and hollow screws for the connections, as well as the control pressure valve, clamp and gaskets. Together these families cover the details that are often replaced during a thorough overhaul of the fuel system.
A wise checkpoint during a rebuild is to always replace the copper washers and O-rings at the same time as the pipes – old washers settle and rarely seal again on reassembly. Also check that the clamps are correctly seated so the hoses do not chafe against surrounding parts.
