Ford’s remedy for the leaks is to add a drain tube to send the gas away from hot surfaces, and a software update to detect a pressure drop in the fuel injection system.
Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).
The 1995-1997 trucks use a two-stage cam-driven fuel pump, whereas the 1999-2003 trucks use a frame rail mounted electric fuel pump. The 1999–2003 trucks also had a deadhead fuel system and a "long lead" injector in cyl. number 8 due to lower fuel pressures with the deadhead design (AE code injector).
Almost 300,000 Ford diesel-engine trucks may be subject to a recall due to a dangerous issue with the fuel pump. The Ford recall will potentially affects up to 295,449 F-series trucks, according ...
The EEC-II controlled air-fuel ratio via Ford's model 7200 Variable Venturi (VV) Carburetor, the last carburetor designed and built by Ford US. In it, the air-fuel ratio was controlled by a stepper motor that operated a rack which moved a pintle that opened and closed the float bowl vent. When closed, no air could enter the bowl, causing the ...
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
The Ford EEC-III single-point fuel injection system, introduced in 1980, was another early digital fuel injection system. [ 56 ] [ 57 ] These and other electronic manifold injection systems (using either port injection or throttle-body injection ) became more widespread through the 1980s, and by the early 1990s they had replaced carburettors in ...
