Description

Genuine Alliant Power remanufactured fuel injector set (8 injectors) for Ford Super Duty trucks equipped with the 7.3L Power Stroke diesel engine.

Each injector in this set is remanufactured to strict OEM-quality standards using premium components and is thoroughly tested to ensure proper fuel delivery, injection timing, and long-term reliability. Every injector undergoes extensive quality control procedures before shipment to help restore factory engine performance and dependability.

This Alliant Power injector set is engineered to:

  • Restore proper fuel delivery and injector performance
  • Improve throttle response and horsepower
  • Reduce rough idle, misfires, and excessive smoke
  • Support smooth engine operation across all eight cylinders
  • Maintain fuel efficiency and combustion performance
  • Improve overall engine balance and reliability

Replacing all eight injectors as a matched set helps maintain proper cylinder balance, smoother operation, and dependable long-term performance. This is often recommended for high-mileage 7.3L Power Stroke engines experiencing injector wear or fueling inconsistencies.

Designed specifically for the HEUI (Hydraulic Electronic Unit Injection) fuel system used in the 7.3L Power Stroke, these injectors provide the precise fuel control required for reliable operation under demanding work and towing conditions.

This injector set replaces Alliant Power part numbers AP63803AD and AP63804AE and compatible OEM references. Fitment is verified before shipment.

Core Policy

What is a turbo core?

A few products in this industry, such as turbos, have a core charge that is associated with the new replacement part.  You must return the old part to receive a refund on the core charge.  All cores must be like for like, and include all parts and pieces that were received on your new replacement product. Cores must be “as removed from the engine.”  Damaged cores from a fire are not acceptable, also cores damaged from improper removal may not be acceptable.

How would you like to handle your Core Return?

Please choose from one of the three options outlined below.

Option #1 – RETURN CORES IN ADVANCE

Customers have the option to ship cores ahead of time. Upon receipt of your Advance Cores, we will proceed with dispatching your order. Please send your Advance Core to:

16601 yucca St. Hesperia, CA 92345

Option #2 – RETURN CORES LATER

The customer will initially incur a Core Deposit charge. A complete core refund is available upon return of the old Cores within 45 days from the initial shipping date. Returns after 45 days might qualify for a partial reimbursement.

Core Return Procedure

DO THE FOLLOWING WHEN RETURNING YOUR CORE:

Use a box strong enough to support the weight of the contents.

Securely seal core/s inside a plastic bag to prevent leakage.

Use at least two inches of appropriate cushioning material to protect items from each other and the corners, sides, top and bottom of the box.

Samperio Turbo Rebuild is not responsible for cores received damaged, freight penalties, and/or lost shipments.

Once Samperio Turbo Rebuild receives the cores, it will be inspected and graded based on Core Criteria, Full or partial refund will be processed within 1 to 3 business days.

Note that Samperio Turbo Rebuild may reject cores or even pay partial credit if Core Criteria are not met.

All shipping Charges are the responsibility of the customer.

Core must be like-for-like.

You must send core complete and assembled. Missing components might affect the percentage refunded.

If the core is returned after 45 days, 50% of the core will be refunded. After 3 months cores will be accepted at Samperio Turbo Rebuild’s discretion.

Cores need to be returned to the address below with a copy of the invoice or RMA so we know whose core it is. Expect delays without that information provided.

or

Return Cores in Advance

Customer returns cores in advance to avoid the core charge.  The order will ship out once we have received the core.
