What should I do about my Isuzu diesel engine?
What should I do about my Isuzu diesel engine?
Protect your customer’s engine from contaminated fuel by recommending regular fuel system inspection and maintenance. This will ensure continued performance of the Isuzu Diesel engine and provide the earliest detection of diesel fuel contamination. Maintenance is the customer’s responsibility.
How to diagnose and repair Isuzu truck with 4JJ1?
If no there is no indication of DEF contamination follow Procedure B. 1.Remove cap from fuel tank. 2.Disconnect suction line from the water separator. 3.Use air to push fuel and contaminants into fuel tank. 4.Reconnect suction line to water separator. 5.Clean the fuel tank. Drain fuel into an appropriate storage container. Remove fuel tank.
Why is my Isuzu truck leaking diesel fuel?
During refueling, it is possible for water (and other contaminants) to be pumped into the fuel tank along with the diesel fuel. This can occur if a service station does not regularly inspect and clean its fuel tanks, or if a service station receives contaminated fuel from its supplier (s).
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
How does Liquid Intelligence fix diesel pump leak?
The Liquid Intelligence 229 Diesel Fuel Pump Seal Leak Fix formulation contains a unique combination of ester and phenol additives. When added to diesel fuel, the ester and phenol chemical combination swells and rejuvenates nitrile diesel fuel pump seals – completely eliminating leaks.
Can a fuel injector cause an internal fuel leak?
Both top feed and side fuel injectors make use of O-rings to seal between the fuel injector and fuel rail. Fuel injector O-rings can harden and become brittle over time especially those on older vehicles. This can cause both external and internal fuel leaks and should be taken care of immediately.
What causes a diesel fuel pump to leak?
The nitrile rubber reacted to the changes in the new fuel composition by shrinking them over time causing the pumps to leak. Most current generation diesel fuel pumps that were manufactured after 2002 had O rings that were made of FKM (also known as Viton) and those seals are not affected by the chemical changes in low sulphur diesel.
Can a fuel injector be tested under pressure?
Fuel injector leak testing should be done under operating pressure. The average DIY fuel injector cleaning project and most automotive repair shops does not have the proper diagnostic equipment or the ability to test leaking injectors or clean them properly.
