NOTE:If air pressure is greater than 827 kPa (120 psi), use a pressure regulator. Prime pump with shop air. Using a rubber tipped air gun to seal around the DEF pump inlet fitting, apply clean regulated shop air to the DEF pump inlet fitting for three to five seconds.

DD15 Engine - Section 1 The Fuel System Detroit Diesel

Jun 06, 2019 · From the fuel accumulator (14) part of the returned fuel is delivered directly upstream of the fuel prefilter (3) in the fuel low pressure circuit. The fuel quantity is determined by the throttle valve (12) and the regulator (13) in the fuel return (17) bypass. This returned fuel leads to a lower suction load for the low pressure fuel pump (4).

I am glad it was under warranty for the customers sake. The doser pressure regulator valve is in the high pressure flange, you have to use a 6mm allen to remove it.

CAUTION:Perform this test only long enough to determine if pressure rises above minimum specification; risk exists of blowing coupler hose off of pump. This test is only necessary if other pressure tests indicate lower than normal fuel pressure. I have am mbe 4000 with code 3480 doser fuel pressure low The most common thing for this code is the doser block assembly malfunctioning or low fuel pressure due to fuel filters or a restriction in fuel system.

Section 2 - Fuel System

Diesel Fuel System without Motor Control Module (MCM) The fuel system includes injectors, integral fuel manifold in the cylinder head, fuel pump, a primary fuel filter, a secondary fuel filter, and a fuel pressure regulator. See Figure "Schematic Diagram of the Diesel Fuel System with MCM" for fuel system diagram. FIRE (f9) losing fuel pressure on my 2011 DD15 Cascadia Apr 18, 2014 · I have a 2011 Cascadia DD15 with 312,000 miles recently when I shut it of it will lose fuel pressure after about 15 - 20 min. It does not have a check engine light so Freightliner in Madison WI cant figure out whats wrong. They have checked the injectors and said they are OK, replaced the fuel filter and base unit for the fuel filter.708-13.pdf - Fuel System Diagram Update17. Pressure Relief Valve 18.
