Fuel system, diesel: storage: tank assemblyReported April 20, 2005 · 253 vehicles affected
What is wrong
On certain trucks equipped with rpo ik9, due to insufficient durability and testing, the fuel switching manifold solenoids lack water or salt intrusion resistance, which can lead to failure of one or more solenoids. Fuel switching manifold solenoid failure will cause incorrect fuel delivery resulting in fuel overflow from the fuel filler neck.
Risk
Overflow fuel may result in high amount of diesel fuel leakage. Fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy
Dealers will replace the solenoid valve assembly with an improved assembly including additional detection circuit and enhanced water resistance free of charge. The recall began on october 27, 2005. Owners may contact isuzu at 1‑800‑255‑6727.
