Contact us before shipping. We will confirm eligibility, pricing, and the mail-in address so your injectors can be matched to the right order.

Drain residual fuel according to carrier rules. Wrap each injector separately; protect tips and electrical connectors. Do not ship loose fuel, leaking injectors, or improperly prepared fuel-contaminated components.
Use a sturdy, well-cushioned box. Include your name, phone, and order number. Use tracked shipping and ask your carrier about hazardous-material restrictions. Inbound shipping is the customer’s responsibility unless agreed otherwise.
We confirm the count, inspect visible condition, verify compatibility, document the set, and begin approved work. We contact you before proceeding if a problem requires additional approval.
Eligible orders received before the daily cutoff are targeted for same-business-day completion; other eligible orders are targeted for the next business day. Timing begins when the package is physically received during business hours.
Your completed injectors, available flow results, service documentation, and return tracking are prepared for shipment. The $25 return-shipping charge is disclosed in your estimate and checkout.
Clear expectations
An injector may fail because of mechanical damage, electrical failure, severe contamination, internal corrosion, leakage, an irregular spray pattern, or unacceptable flow imbalance. We document available findings and notify you. No replacement, extra repair, or additional cleaning charge is added without authorization. You may request return of the failed injector or approve another eligible cleaning attempt for an agreed fee. If it cannot be safely tested, we explain the limitation.
Completed inspection, testing, and cleaning remain chargeable even when an injector cannot be restored. If an injector is rejected before paid service begins, you are not charged for unperformed work. Replacement injectors are not included in cleaning prices.
Our target is same- or next-business-day processing after receipt for eligible injectors. Delays may result from carrier issues, missing information, incompatibility, severe contamination, equipment malfunction, unavailable parts, unexpected testing complications, high volume, holidays, or closures. We will contact you as soon as reasonably possible with the reason and an updated estimated completion date.
You may request return of unserviced injectors, subject to completed-service charges and return shipping. If a paid rush deadline is missed because of our operations, the rush surcharge is refunded. This does not apply to inbound shipping delays, missing information, or circumstances outside our control.
Customers are responsible for safe packaging and inbound shipping. We recommend tracked and insured service. Visible shipping damage is documented on arrival and reported to you. Houston Injector Performance exercises reasonable care while injectors are in our possession; claims involving damage, loss, or service errors are reviewed individually.
By approving service, you authorize the selected cleaning, inspection, and testing procedures. You acknowledge that cleaning does not guarantee repair; results describe the condition observed under the specified test conditions; some injectors may be unsuitable for service; additional work requires separate approval; and vehicle installation, tuning, and final operating verification remain the customer’s responsibility.
