On a 6.0L or 7.3L Power Stroke (the 6.4L and the 6.7L are common rail engines much like the Duramax or 5.9/6.7L Cummins), the injectors are essentially the high-pressure pump. There is no CP3 to ramp the pressure to 28,000 psi. Other fuel pump companies may rate their fuel pumps at a given psi. For example the Walbro fuel pumps that we sell are rated at 40 psi. Our most popular fuel pump we sell is the 4 series fuel pump assembly. These assemblies use a Walbro 255 lph fuel pump. 255 liters is the volume of fuel that the pump will flow at 40 psi.

Jun 03, 2019 · When a fuel pump completely malfunctions, fuel cannot get to the engine upon ignition. If this happens, the engine will crank and rev but never start. To diagnose a fuel pump malfunction, check for low pressure in the fuel line and/or a blown fuse . 6. Power Loss. A car is put under huge stress when climbing a hill or hauling heavy cargo.
Apr 05, 2020 · A diesel fuel lift pump is a lift pump that transfers fuel from the tank to the fuel injection system. Because in modern vehicles the tank is located below the engine, the fuel has to be lifted up from the tank to the engine, which the diesel fuel pump does.
A high-pressure system leak can be indicated if the sensor output rapidly drops to 0.5 V after the engine has been stopped, as might occur with a leaky injector, rail pressure regulator, inlet metering valve or pump.
Automotive fuel systems consist of many components, the fuel tank, fuel pump, filter, lines, injectors, etc. One component in high pressure fuel systems is a high pressure fuel pump. It's job is to increase the fuel pressure for the very high pressure needed at the fuel rail for the injectors.
It is a definite lift pump that was manufactured for the models of Ford between 1999 and 2003. It has a high fuel pressure regulator from around 50 to 55 psi. This lift pump replaces the factory high-pressure pump. It consists of a dual gerator pump that gives it a unique feature than the rest of the lift pump.

When It Comes To Universal Fuel Pumps, Airtex Has You Covered Airtex universal fuel pumps undergo the same rigorous design validation standards and production line testing as the rest of the Airtex fuel pump lineup.
  • The Fuel Pump This type of high pressure fuel pump is denoted as a roller cell pump, with the fuel entering the pump and being compressed by rotating cells that force it through the pump at high pressure. The pump is capable of producing a pressure of 8 bar (120 psi) with a delivery rate of approximately 4 to 5 litres per minute.

Sep 12, 2011 · Injection System . No matter how you look, the main objective of air injection is free. Loosen the fuel lines is a common practice for older diesel vehicles. Loosen fuel line fittings before the injection pump works the hand pump until no more air bubbles streaming from loose fuel lines to see.

Modern diesel cars (since 2009) have to be fitted with a Diesel Particulate Filter (DPF) in the exhaust to stop this soot passing into the atmosphere. The aim is an 80% cut in particle emissions but the technology's not without problems and our patrols are often called to cars with a blocked DPF. Bosch Port Fuel Injectors (PFI) have a robust design and are capable of using Ethanol fuel (E100). All Bosch fuel injectors released to the aftermarket are OE fit, form and function, and are produced to OE specifications. The Bosch fuel injector has a return rate of 1 part per million (PPM), making Bosch the industry benchmark.
I have a 98 Chevy truck 1500 v8 350.I have changed fuel pump,fuel filter,fuel relay,starter relay, and fuel pressure regulator.it will start then stays on for a min then shuts off like ran out of gas.I have replaced fuel pump twice thinking I got a bad one.today went got ignition switch and ignition module no luck will not stay running.please help how to re-wire a fuel pump off a relay. on your web site it shows this diagram with #85 going to ground. in the wiring in the fuel pump relay #2. it states # 86 goes to ground. i am a non-wiring person, i have a bosch relay # 0 332 209 150-896. please advise.

In order to obtain the near perfect air/fuel ratio in today’s engines, the injector must meter and deliver a precise amount of fuel into the intake runners. The correct fuel flow and spray pattern can only be achieved, over a long period of time, through a well-maintained injector.

As for the 6.4L diesel engine, one critical difference between it and the 6.0 is that the 6.4L engine does not use a high-pressure oil system for fuel injector operation. It uses a high-pressure pump, but it’s pressurizing diesel fuel, not oil.
