Honda 1.5T HPFP Replacement: What to Verify

Buying Guide · September 2026 · 7 min read

Replacing a Honda 1.5T high-pressure fuel pump (HPFP) is not simply a matter of searching for “Honda fuel pump” and choosing the first matching listing.

The 1.5T GDI fuel system uses an engine-mounted high-pressure pump, which is different from the low-pressure fuel pump inside the tank. For workshops and B2B buyers, the critical steps are identifying the correct pump, checking the part number, confirming vehicle fitment, and verifying the actual stock before ordering.

For the Honda 1.5T HPFP currently listed by YUDI Auto Parts, the key reference is Honda 16790-5PC-H02 / Denso 296100-0726.

1. Confirm You Need the High-Pressure Fuel Pump

The first mistake is confusing the HPFP with the in-tank fuel pump.

A Honda 1.5T direct-injection system can contain several fuel-delivery components, including:

• In-tank low-pressure fuel pump
• Fuel feed components
• Engine-mounted high-pressure fuel pump
• Fuel rail
• Fuel pressure sensor
• Fuel injectors

These parts are not interchangeable.

If the repair order specifically calls for an engine-mounted high-pressure fuel pump, do not quote a generic “Honda fuel pump.” State the component type clearly when requesting a quotation.

This distinction is especially important because Honda has also had separate fuel-pump recalls involving different components and vehicle applications.

2. Check the Honda Part Number Before Ordering

For the Honda 1.5T HPFP stocked by YUDI Auto Parts, the primary reference is:

YUDI’s current product data identifies 16790-5PC-H02 with Denso 296100-0726 and lists applications around Honda 1.5T GDI engines.

However, part-number verification should not stop with the first number you find.

Some catalogs list 06161-5PC-315 as a service reference for the 1.5T application. That reference should be treated as a catalog cross-reference to verify against the vehicle, not as a confirmed supersession.

For this reason, ask the supplier whether the quoted number is:

1. The exact requested part number
2. An official supersession
3. A different OEM reference
4. An aftermarket replacement

That distinction can prevent unnecessary returns. For the full breakdown of how the Honda GDI pump numbers relate, see Honda GDI HPFP Part Numbers: 5PC vs 5LA, 0726 vs 0054.

3. Match the Vehicle, Not Just “1.5T”

“1.5T” is useful information, but it is not enough to guarantee fitment.

Published catalog data associates 16790-5PC-H02 with applications including certain Honda Accord, Civic and CR-V 1.5T models. One current catalog lists Accord applications from 2018–2022, Civic Si applications from 2017–2020, and CR-V applications from 2017–2022.

YUDI’s current product page also identifies L15BE and L15B7 1.5T GDI applications across Civic, CR-V and Accord, while noting that VIN confirmation is recommended because application can vary.

Before purchasing, provide as much of the following information as possible:

• VIN
• Model year
• Exact model
• Engine code
• Trim
• Transmission
• Market or country
• Original pump part number

For imported vehicles, VIN verification becomes even more useful because regional specifications can differ.

4. Check the Number on the Existing Pump

If the original pump is still available, ask for clear photos before it is removed from the vehicle.

Useful views include:

• Honda part number
• Denso/manufacturer number
• Label or stamping
• Electrical connector
• Fuel-line connection area
• Overall pump housing

For example, if the existing unit shows 16790-5PC-H02, you can ask the supplier to confirm the corresponding Denso reference and current replacement option.

This is more reliable than sending only:

“I need a Honda Civic 1.5T fuel pump.”

A complete part-number request gives the supplier something specific to verify.

5. Ask for Actual Stock Photos

A catalog photograph proves that a product exists on a webpage. It does not prove that the exact item is currently in stock.

For a high-value fuel-system component, ask for photographs of the actual unit before purchasing.

Useful photos include:

• Pump body
• Denso logo
• Manufacturer marking
• Part number
• Batch or production marking
• Packaging label
• Sealed packaging, where applicable

YUDI’s current sourcing process specifically provides actual stock photos and can provide batch-number and packaging-label photos on request. For what those markings should look like on a genuine 296100-0726 unit, see How to Spot a Genuine Denso 296100-0726.

This is particularly useful for B2B buyers purchasing multiple units, because the photos provide an additional verification point before payment and shipment.

6. Do Not Mix 1.5T and 2.4L HPFP References

Honda’s GDI high-pressure pumps can look similar in online listings, but the part numbers are not automatically interchangeable.

For example:

YUDI’s current part-number data keeps these two applications separate, and the 2.4L side has its own fitment reference.

If a quotation contains both 5PC and 5LA references, ask the supplier to identify exactly which vehicle application each number represents.

Do not assume that a similar-looking pump is a direct substitute.

7. Exact Replacement vs Aftermarket Alternative

An aftermarket HPFP may be appropriate for some repair situations, but buyers should identify what they are actually purchasing.

Before accepting an alternative, check:

• Manufacturer
• Exact OE cross-reference
• Vehicle application
• Fuel-system compatibility
• Warranty terms
• Packaging
• Traceability
• Actual product photos

For repair shops and distributors, the purchase price is only one part of the calculation.

An incorrect component can create additional labor, vehicle downtime, customer complaints, and international return costs.

For this reason, verified OE sourcing can be useful when the priority is reducing fitment and identification uncertainty.

8. What to Include in a B2B RFQ

If you are sourcing Honda 1.5T HPFPs for a workshop or distribution business, a short but complete RFQ can save several rounds of messages.

Use this format:

If you have multiple part numbers, send the complete list together.

A supplier can then check availability, identify exact references, and separate confirmed stock from items that require sourcing. For the wider version of this request format, see How to Create an Auto Parts RFQ That Gets Accurate Quotes.

When Should You Order the Replacement?

The replacement decision should follow a proper vehicle diagnosis.

A high-pressure fuel pump should not be purchased solely because a vehicle has poor acceleration, a check-engine light, or a fuel-pressure-related fault.

Those symptoms can have multiple causes — which is why a returning fault code after a replacement still needs the same part-number and application checks before another pump is ordered, as covered in Honda 1.5T HPFP: Why P0087 May Return.

Once the workshop has identified the HPFP as the component requiring replacement, the sourcing process should then be straightforward:

1. Identify the existing part number.
2. Confirm the vehicle and engine.
3. Check exact or superseded OEM references.
4. Confirm supplier stock.
5. Request actual product photos.
6. Verify packaging and batch information where available.
7. Confirm the quotation before shipment.

This workflow helps separate diagnosis from parts identification, reducing the risk of ordering the wrong component.

How YUDI Auto Parts Verifies Honda 1.5T HPFP Stock

YUDI focuses on sourcing rather than repair diagnosis.

For the Honda 1.5T/2.4L GDI HPFP line, the current process includes:

• Verified Stock — availability is checked against actual inventory.
• Actual Photos — buyers can receive photos of the actual unit.
• Batch Traceability — batch information can be photographed on request.
• Fitment Confirmation — VIN or existing part-number information can be checked before quoting.

The current YUDI site states that it only lists products it can photograph and verify, while other Honda and Toyota components can be sourced by part-number request.

For overseas repair shops and distributors, the objective is simple: know what part you are buying before it ships.
