What should my fuel pressure relief valve be?
What should my fuel pressure relief valve be?
Your typical truck usually isn’t up around the 28K range. I believe the standard he does is around 24K to 25K. Different size washers are used to achieve the blow off desired.
What’s the return flow test on a 6.7L diesel?
Fuel pump return flow test:Measures the ability of the high pressure fuel pump to provide specified return fuel volume. when working on the 6.7L fuel lines it is tempting to bend the lines out of the way to get at items or tube nuts.
What is the high pressure fuel pump psi?
The high pressure fuel pump supplies high pressure fuel as high as 300-1800BAR or 4351-26107 PSI to each injector through the high pressure lines. Fuel under this amount of pressure can penetrate the skin and cause personal injury or death.
How to diagnose high pressure fuel system?
The high pressure fuel system can be diagnosed using a scan tool. high pressure fuel pump flow: tests the ability of the high pressure fuel pump to supply fuel volume. This is a go-no-go test. If fuel is present , further testing is necessary
What’s the normal fuel pressure in a 6.7 L engine?
All 6.7 L engines use an in tank style supply pump like the later 5.9 L engines. There are also supply pumps that mount on the frame rail and replace the in tank supply pumps, such as the FASS pump. Test the supply pressure at the inlet to the CP3 pump. Normal pressure is 10 PSI at idle and they typically drop close to zero PSI under load.
What’s the fuel pressure on a 2012 Ram 3500?

What’s the high pressure limit for fuel injection?
If the injector connector tubes, where they seat into the injectors, leak or the check ball in the injector is leaking or the high pressure limit valve then it will not build enough rail pressure to start the engine. It takes approximately 4000 PSI rail pressure for starting. The fuel system contains high pressure fuel up to 26,000 PSI.
