The lift pump on a 6.7L only runs at around 10 psi. The fuel rail pressure on the other hand can be as high as 20,000 psi.
The usually have 5000 to 7000 psi at start up.
Lift pump pressure is only about 10 psi. Cummins actually does not put a spec on it. They put a spec on how much volume the pump is putting out. Should be more that 500ml in 30 seconds. The high pressure side of the system will vary from 5000 psi to 20,000 psi.
Fuel pressure sensor for a 2009 LAND ROVER LR2 costs about $950.
where is the fuel pressure at
how much fuel pressure should a 1999 Isuzu amigo have
the fuel pressure should be 65 pounds of pressure
Restricted fuel return line or a faulty fuel pressure regulator.
Just a short burst at pressure. It is not so much the volume but the pressure I look for. Fuel pumps are the #1 problem on these models.
The fuel pump pressure is what allows the fuel to flow to the engine. It determines how much goes in and also when.
Normal fuel pressure runs between 14 to 18 PSI on most fuel injected gasoline engines.
You can get a re-manufactured cummins for around $8000.00.
The 4.3L engine in 2002 should have 60 to 66 psi of fuel pressure.
