YUANTUO Turbo Vacuum Harness & Wastegate Boost Solenoid for Ford 1999–2003 7.3L — Direct-Fit, Pre-tested

YUANTUO turbo emission vacuum harness connection line and wastegate boost solenoid replace factory parts on 7.3L Powerstroke Ford Super Duty trucks from 1999–2003 for reliable vacuum routing and turbo control.

If your 7.3L Powerstroke-equipped Ford F-250, F-350, F-450, F-550 or Excursion is showing inconsistent boost behavior, exhaust backpressure issues, or check-engine codes tied to vacuum routing, worn or failed vacuum harnesses and boost solenoids are common culprits. This YUANTUO kit includes a direct-fit vacuum harness connection line and a wastegate boost solenoid designed to match the original equipment form, fit, and function for model years 1999–2003. Parts are made from durable plastic materials with protective sleeving and are pressure-tested before shipping to help restore correct turbo control without complex modification.

How does this replacement improve turbo control on older 7.3L Powerstroke engines?

Replacing brittle or cracked vacuum lines and a failing boost solenoid restores the proper vacuum signals to the wastegate and turbo actuator so boost regulation returns to factory behavior. That stabilizes turbo response and helps avoid over- or under-boost conditions that affect drivability.

• Direct replacement for factory routing and connections to prevent leaks.
• Durable synthetic plastic shell resists abrasion and corrosion.
• Pre-tested assemblies reduce risk of installation-related failures.

Will this fit my Ford Super Duty or Excursion from 1999–2003?

Yes — the kit is built specifically for Ford 7.3L Diesel Powerstroke engines installed in F-250, F-350, F-450, F-550 (1999–2003) and Excursion (2000–2003) trucks. It replaces the factory part numbers to ensure an exact match for mounts and vacuum ports.

• Replaces F81Z-9E498-DA (vacuum harness connection line).
• Replaces F81Z-6C673-AA (wastegate boost solenoid).
• Fits 7.3L Powerstroke wiring and vacuum layouts without splicing.

What materials and quality checks are used in this YUANTUO kit?

The harness is wrapped in a synthetic plastic shell to protect wiring and vacuum tubing from wear and environmental damage, while the solenoid is built to resist corrosion and heat common in engine bays. Each unit undergoes functional testing before shipping to ensure connections and valves operate as intended.

• High-quality, wear-resistant plastics for longer service life.
• Corrosion-resistant components suitable for engine bay conditions.
• 100% rigorous testing to confirm operation prior to dispatch.

How easy is installation and what comes in the package?

The kit is designed for straightforward replacement using the OEM mounting points and vacuum ports; basic hand tools are typically sufficient for installation. The package gives you both the vacuum harness connection line and the wastegate boost solenoid so you can address common vacuum-related boost issues in one service.

• Includes 1 vacuum harness connection line and 1 boost solenoid.
• Direct-fit design — no cutting, splicing, or custom brackets required.
• Backed by a 24-month service and hassle-free return policy.

Who is this for: This replacement kit is for owners and mechanics working on Ford Super Duty trucks and Excursions equipped with the 7.3L Powerstroke from model years 1999–2003 who need to restore correct vacuum routing or replace a failed wastegate boost solenoid. It suits DIY enthusiasts wanting direct-fit parts and professional shops seeking reliable, tested components that meet or exceed original specifications.
