Know Your Vehicle: The 4 Types Of Diesel Fuel Pumps

For every 100 cars sold in the United States, one diesel engine car is sold. If you’re among this population of diesel-engine users, make sure that you know what type of diesel fuel pump you have.

 

    1. Common rail fuel injection pump. An electronically controlled diesel fuel supply system, this pump was developed to meet the strict 21st century exhaust gas regulations. It consists of a supply pump, common rail, electronically controlled injectors, a variety of sensors to detect the engine’s running condition, and a computer that controls all of these devices. The engine drives the supply pump, which produces high-pressure fuel. The common rail distributes the fuel to the injectors, which are mounted on each cylinder of the engine.
    2. Distributor (rotary) fuel injection pump. This diesel fuel pump is also controlled electronically by various sensors, an electronic control unit, and an actuator. Similar to the common rail pump, the sensors detect the engine’s running condition and send signals to the control unit. The actuator controls how much fuel is injected and its timing according to the signals it receives from the control unit. The control unit determines what signals it sends by calculating the optimum levels for the engine’s running condition.
    3. In-line fuel injection pump. One of two mechanically controlled diesel fuel systems, the in-line fuel injection pump matches the engine cylinders in their number of fuel pressure mechanisms. This pump is primarily used for medium to large trucks and construction machinery. A camshaft drives the fuel pressure and injection quantity control mechanisms within the pump body. The elements in that body follow an injection order to feed fuel to each engine cylinder.
    4. Distributor injection pump. Also a mechanically controlled diesel fuel pump, the distributor injection pump has just one fuel pressure mechanism, despite the number of engine cylinders the vehicle may have. The distributor is designed to follow the injection order to distribute pressurized fuel to each cylinder. The pump housing holds all of its components, including the governor, timer, and feed pump. As it is so compact, this pump is light and can operate at high speeds, making it perfect for small engines.

Knowing your vehicle’s exact type of diesel fuel pump is important in case it shows signs of needing replacement, which can include sudden surges in speed, rising car temperatures, decreased gas mileage, and more. If you experience any of these indicators, take a look at diesel pump manufacturers or fuel pump manufacturers to see if you need a replacement today.

Why Your Diesel Engine Could Benefit From an Aftermarket Lift Pump

When it comes to your diesel application or any application for that matter, eventually stock just doesn’t cut it. Factory parts and mechanics can serve you well for many years but ultimately there is a need to upgrade the performance of your diesel engine. Upgrades can get tricky and most of them are contingent on completing prep-steps before any part swapping can be completed.

One of the parts that end up being replaced with a higher performing model is the diesel fuel lift pump.

What is a lift pump?

Basically, it’s a fuel supply pump that takes fuel from the tank and transfers it to the injection system. Typically, most diesel engines are equipped with some sort of fuel pump whether it’s a mechanical injection system found in older models or the new models where the pump is integrated into the engine itself.

Why would you need a new one?

Upgrading engines with aftermarket and performance parts isn’t a new concept and frankly transcends even the diesel world. Just about anyone and everyone wants to upgrade something about their engine, whether gas, diesel, or vegetable oil (not sure how many upgrades are available for a deep fryer, though). Despite the fact that a diesel engine holds the top spot for the most efficient internal combustion over all other engine types, adding a new pump to your diesel engine can vastly increase its performance well past the factory limits.

How would you go about it?

The goal of the modification is to increase the amount of fuel that’s being injected into the engine. You would need to start this process by increasing fuel flow with computer programming (newer models) or by installing high-flow injectors. With the engine demanding more fuel, you’ll inevitably need to upgrade your pump. Bad fuel pressure means less horsepower and, in some cases, damage to the injection pump.

When deciding which lift diesel lift pump to purchase, it’s important to remember that first word: diesel. There are gasoline pumps that can be retrofitted for a diesel application but will ultimately fail, sometimes immediately. Consider opting for a pump and filter combination which offer performance as well as better and higher capacity filtration.
