Dt466e Fuel System Diagram Fuel issue. on top of the filter screen area of your primer pump there is a plug. remove the plug and there is a check ball. these check balls can be a problem (older ones fall apart) and can be easily replaced with a new upgraded check ball. like. The fuel goes through the primary filter to the transfer pump. (suction side) then fuel goes back to the secondary filter then to the main pump. (transfer pump pressure side) there should be a way to check transfer pump pressure but i have never done it. i suspect you have an issue in the transfer pump but i would try to fix the primer pump first.
International Dt466 Engine Symptoms Diagnostics Priming Fuel System The fuel system in dt466 engines is complex, and diagnosing issues within it requires a systematic approach. common problems include clogged fuel filters, issues with the fuel injectors, or problems with the fuel pump. symptoms of these issues can range from engine stuttering to a complete failure to start. the first step in diagnosis is often. • if unit was run out of fuel, make sure the fuel system was primed. see “priming the fuel system” in section 4 (page 132) for procedure. • see “combustion leaks to fuel” in section 4 (page 104) if all three of the following conditions are noted: • fuel system will not prime • white to black exhaust smoke • pulsating fuel pressure. 1999 dt 466e in an international 4700. starts and idles fine. drive it a few hundred feet it starts sputtering. hit the schrader and lots of air comes out before you get solid stream of fuel again. pulled tank, pickup tube is fine. vent is ok. changed primary filter. still getting air. Fuel system issues injector problems. the injectors in the dt466 are critical for its operation. when they malfunction, symptoms like rough idling, power loss, and increased fuel consumption are common. regular maintenance and timely replacements are crucial to avoid these issues. fuel filter and line blockages.

Follow the line from the tank to the engine, crack the line loose the first place it connects, have someone crank the engine and tighten the line when you got clear fuel, move to the next joint repeat. then crack all the lines loose on the pump and crank it til you get a nice stream of fuel out the lines. Life expectancy and specifications of international's dt466 engine. typically, a well maintained engine has a life expectancy of 550,000 miles before needing to rebuild it. that's equivalent to 16 20 years of operation. after that, you can use an easy and affordable in frame rebuild process at a fraction of the cost of a new diesel engine.
