HOW MUCH DOES A DIESEL INJECTOR COST?

Diesel Injector Options and Part Costs

There are two main types of diesel injection used. The simpler version utilizes a diesel injection pump, which both generates fuel pressure and distributes fuel to each injector. These use relatively simple injectors, since most of the fuel management occurs at the injection pump. The injectors are therefore less expensive, but the injection pump itself is commonly replaced on higher-mileage vehicles.

Newer diesel engines use common-rail direct injection. They still use either a centrally-located injection pump or a high-pressure fuel pump, but instead of connecting directly to each individual injector, they meter fuel to a fuel rail, which each injector is attached to. V6 or V8 engines will have a fuel rail with 3 or 4 injectors on each cylinder bank, while inline engines use a single rail that feeds all the injectors. The injectors are individually controlled, meaning each one has its own electronic element. This system is easier for the ECU to control, meaning better performance, efficiency, and emissions, but now that each injector is electronic rather than just a mechanical nozzle, they are more complicated, and in turn more expensive as well.

Injection pumps usually start around $600-700 for a quality remanufactured unit, and go up from there for either a brand-new unit or one remanufactured by the original manufacturer. Individual mechanical injectors start at around $200 each, and common-rail electronic injectors are usually $300 or more. Keep in mind while your vehicle only has one injection pump, it will have an injector for each cylinder, so they can add up quickly. While you can replace a single injector, they all wear at about the same rate. Replacing the entire set at the same time is better for long-term reliability, and will likely save you money on purchase price and labor expenses as well.

Why do labor times vary so much?

Labor on diesel engines is traditionally more expensive than on gas vehicles. First, they aren’t terribly common, so it’s advised to find a diesel specialist, and the specialized training they receive usually means a higher hourly labor rate. They’re also just harder to work on. Because diesel engines operate at much higher compression than gasoline engines, they need to be built stronger, which means they are larger and heavier, making access to them a lot more difficult. On Ford Super Duty pickups, some jobs are easier to complete if you remove the truck’s entire cab from the frame, since space inside the engine bay is at a premium.

Find Your Diesel Injector

With the rate at which automotive technology is advancing, diesel cars are getting more efficient, and diesel trucks are getting more capable, but this advancement comes at a price. Fortunately, the automotive aftermarket is stepping up with quality new and remanufactured parts, even for these unique applications, so it’s easier than ever to keep one of these famously reliable vehicles running for hundreds of thousands, or even a million miles and beyond.

More Vehicle Specific Estimates & Costs

Some of our top-selling diesel injectors, their compatible vehicles and their approximate costs are listed below. Keep in mind that part condition matters, in some cases we offer an aftermarket new part which meets or exceeds OE quality. The last note to be made about this table is that dealerships tend to sell their diesel injectors at list price or close to it, here at BuyAutoParts.com we offer you more than just the original equipment part, as we have aftermarket new, and in some cases have rebuilt injectors.

If you are a DIYer, you will not incur any labor costs. If you choose a professional for the job, you will need to pay for both the part and labor. Here are the approximate diesel injector installation costs specific to some automobiles.
