2017 Honda Pilot High Pressure Fuel Pump Location: Where It Sits and How to Find It
The high pressure fuel pump on a 2017 Honda Pilot is mounted on top of the engine, bolted to the front cylinder head (the bank closest to the radiator), driven directly by the camshaft, and it is easy to see once the plastic engine cover is removed. It is a small, upright, metal cylinder about the size of a closed fist, sitting near the intake manifold on the front bank of the 3.5L V6. A hard steel fuel line runs from the top of the pump to the high pressure fuel rail, and an electrical connector is attached to its body. If you are standing in front of the vehicle and looking back into the engine bay, the pump is on that front-facing cylinder head, offset to one side of the intake plenum. Nothing has to be removed from underneath the vehicle to locate it, and no lift is required.
That single paragraph answers the question most owners arrive with. The rest of this article explains what the pump does, how to reach it safely, what surrounds it, what symptoms lead people to look for it, what to check before replacing it, and where to buy a dependable replacement for the 2017 Pilot.
1. Why the 2017 Honda Pilot Has a High Pressure Fuel Pump at All
The 2017 Honda Pilot uses a 3.5-liter V6 from Honda's J-series engine family, and this version uses gasoline direct injection. In a direct injection engine, fuel is sprayed straight into the combustion chamber at pressures far higher than a conventional port-injection system uses. The fuel pump inside the tank, often called the low pressure or in-tank pump, cannot create that level of pressure on its own.
The job of the second pump is to take the fuel delivered by the in-tank pump and compress it to the much higher pressure the injectors need. Because that work is done mechanically, the pump is mounted on the engine itself instead of inside the fuel tank. The camshaft drives it through a lobe, which is the reason the pump has to sit on the cylinder head rather than anywhere else in the engine bay.
Once you understand that the pump is engine mounted and camshaft driven, the location makes complete sense. It has to be on a cylinder head, and Honda placed it on the front bank of the V6 where it stays reachable from above.
2. What the Pump Looks Like and How to Recognize It
Most people searching for the location have never seen the part before, so it helps to know its shape before opening the hood.
On the 2017 Pilot, the high pressure fuel pump is:
- A short metal cylinder, standing upright on the cylinder head, with a rounded or stepped top section.
- Connected to a thick steel line that leaves the pump and runs to the fuel rail, which is the metal pipe feeding the injectors along the cylinder head.
- Fitted with an electrical connector on its body, because the pump uses a control signal to manage output pressure.
- Bolted down with two or three small fasteners into the cylinder head, with a seal between the pump and the head.
- Fed by a lower-pressure line coming from the chassis or the in-tank pump, which attaches to the side or bottom of the body.
It is not the ignition coil, it is not the fuel injector, and it is not part of the variable cylinder management hardware. The giveaway is the hard fuel line on top and the upright metal body sitting directly on the head casting.
3. Step-by-Step: How to See the Pump on Your Own Pilot
You can locate the pump with no special tools beyond a basic socket set and a trim tool, and the job is done entirely from the top of the engine.
- Park on level ground and shut the engine off. Let the engine cool if it has been running, because the pump and the surrounding head get hot.
- Open the hood and find the plastic engine cover that sits across the top of the V6.
- Remove the engine cover. On most 2017 Pilot trims, the cover is held by a small number of bolts, or it lifts off after the oil filler cap is unscrewed, depending on how the cover is secured.
- Look at the front cylinder bank, which is the one nearest the radiator and the cooling fans. The cylinder head on this bank is where the pump mounts.
- Scan near the intake manifold runners. The upright metal cylinder with a steel line going up to the fuel rail is the high pressure fuel pump.
- Confirm by tracing the line. Follow the steel line from the pump to the fuel rail and then to the injectors. That confirms the part you found is the high pressure pump and not another component.
From the front of the vehicle looking rearward, the pump faces you. The rear bank of cylinders sits behind it, closer to the firewall, but you do not need to reach that far back.
4. Why the Location Matters When Something Goes Wrong
Owners usually start looking for the pump because of a symptom, not out of curiosity. The location on the front cylinder head affects how each symptom is checked.
Hard starting or long cranking. If the engine turns over longer than normal before it fires, the rail pressure may not build quickly enough. Because the pump is on the front head, a technician can access the lines and the connector without major teardown.
Rough idle or hesitation under load. A pump that cannot hold pressure when you accelerate can cause a stumble. The pump's position on the head means the noise and the pressure behavior can be observed directly with the cover off.
Check engine light with fuel rail pressure codes. Codes pointing to rail pressure performance send people to this part first. Being on top of the engine makes a scan, a visual check, and a leak inspection straightforward.
Ticking or tapping from the top of the engine. The pump makes a rhythmic tick by design because it is camshaft driven. A change in that sound, or a much louder tick, is easier to trace when you know the pump sits right there on the front head.
The pump lives in a hot spot, bolted to the head, but that is normal for this design. Heat exposure is expected and is part of why a quality replacement matters.
5. What Sits Around the Pump
When the cover is off, several parts share space with the pump on the front cylinder head. Knowing them stops you from confusing one part for another.
- Intake manifold. The large assembly that routes air into the cylinders. The pump is near where the intake runners meet the head.
- High pressure fuel rail. A metal rail running along the cylinder head that feeds the injectors. The pump's steel line connects here.
- Camshaft cover and head casting. The pump bolts into the head through this area, which is why the pump must sit on a cylinder bank.
- Low pressure supply line. A line coming from the in-tank pump that feeds the high pressure pump before compression.
- Wiring harness connector. Carries the signal that controls pump output.
- Ignition coils and injectors. These sit nearby but are separate. The coils have electrical connectors only, and the injectors sit under the rail, not on top of the head as an upright cylinder.
6. Checks to Do Before Replacing the Pump
Replacing the pump is a real repair, so a few checks should come first. Doing them in this order prevents replacing a part that was never the problem.
- Scan for codes. Use an OBD-II scanner to see whether fuel pressure codes are stored and whether they point to the high pressure side or the supply side.
- Test the in-tank pump. The low pressure pump feeds the high pressure pump. A weak supply from the tank will look almost identical to a failed high pressure pump.
- Inspect for leaks. Look at the pump body, the steel line to the rail, and the supply line for wetness, staining, or a fuel smell.
- Listen to the pump sound. A steady tick at idle is normal. Grinding, whining, or no sound at all is a reason to look closer.
- Check the connector. Make sure the plug is fully seated and the wiring is not cracked, burned, or loose.
- Confirm fuel quality and delivery. Contaminated fuel or a restricted filter can affect pressure readings on both the low and high side.
Only after these checks point to the pump itself should replacement be considered.
7. What Replacement Involves on This Engine
Because the pump is on the top of the engine, replacement is done from above. No subframe is dropped and the vehicle does not need to be lifted to reach the pump.
The basic sequence is:
- Depressurize the fuel system. The high pressure side holds pressure even when the engine is off. This step is not optional and must be done before any line is opened.
- Remove the engine cover to expose the front cylinder head.
- Disconnect the electrical connector on the pump body.
- Remove the fuel lines from the pump, using the correct line tools and catching any residual fuel.
- Unbolt the pump from the cylinder head and lift it out.
- Replace the seal or gasket. The old seal should not be reused.
- Install the new pump, torque the fasteners to specification, reconnect the lines and the connector, and reinstall the cover.
- Check for leaks and clear codes. Start the engine, inspect the area, and re-scan to confirm the pressure codes do not return.
The location on the front head is the reason this job stays a manageable one for a shop, and it is also why a correct direct-fit replacement matters for the line routing and the bolt pattern.

9. Practical Notes for Pilot Owners
- The pump is a wear item over high mileage. Direct injection hardware works under constant high pressure, so age and miles matter.
- Ticking is not always failure. Compare the sound before assuming the part is bad.
- Fix the supply side first. A weak in-tank pump will make a healthy high pressure pump look faulty.
- Never open a fuel line without depressurizing. High pressure fuel is dangerous.
- Use a new seal. Reusing the old gasket invites a leak at the head.
- Verify after the repair. Leak check and re-scan are part of finishing the job correctly.
Final Answer on the Location
On a 2017 Honda Pilot, the high pressure fuel pump is on top of the engine, bolted to the front cylinder head near the intake manifold, camshaft driven, and visible from above once the plastic engine cover is removed. It is the upright metal cylinder with a steel line running to the fuel rail. That location is what makes inspection, diagnosis, and replacement possible from the top of the engine bay without lifting the vehicle.
