Freight/Oversize Shipments
Freight/LTL shipping quotes are calculated based on delivery to commercial addresses. This means that the property must be commercially zoned and have official business hours of operations. If you do not have a business address and you have already purchased a Freight or Oversized item then we will contact you with an updated shipping charge that must be paid for delivery. If you have not purchased yet and would like a shipping quote to a non commercial address, we are more than happy to help!
When a Freight shipment arrives do not sign the delivery receipt before you have fully inspected the package and have marked down the exceptions and damages on the receipt if they apply. If a Freight shipment does arrive and is damaged, we can not help you if you did not sign for it as damaged and clearly note it on the delivery receipt.
Upon delivery of the shipment, if you do not have the ability and/or equipment to unload your product the freight carrier may ask if you would like to have them unload the product with a lift gate or other methods. Any additional services requested such as this may incur an additional fee charged to the customer by the freight carrier and Advanced Truck Parts is not responsible for such charges. The decision to accept these charges lies solely with the delivery recipient.
Free Shipping Promotions
All Free Shipping items will ship either USPS or UPS and will have a 3 to 7 day transit time. For any products or promo codes that offer Free Shipping on orders or individual parts, the Free Shipping only applies to the contiguous 48 United States. For all other ship to locations, an accurate shipping quote must be calculated and paid. Free Shipping also does not apply to oversized or freight items unless specifically stated and a commercial zone address is required.
Canada Shipments
Applicable for Ground Shipments Only - Canada Customs requires Canadian recipients to pay applicable duties and taxes on each shipment entering Canada. These charges may include POST, GST, HST, duties and other taxes of goods. A brokerage fee may also be charged to process shipments and present the requisite customs paperwork to Canada Customs on the importer's behalf. In some cases, orders may be sent in multiple shipments and can incur additional brokerage charges imposed by Canada Customs. The customer is responsible for brokerage fees, POST, GST, HST, duties and other taxes of goods that are imposed by shipping companies or Canada Customs. In the event the customer refuses to pay those fees, Advanced Truck Parts may be forced to abandon the product at the Canadian border. In that case, the customer will receive no refund back because the product will be lost. *Note - No additional taxes or duties are due for Freight/LTL shipments
International Shipments
At Advanced Truck Parts we are proud to provide international shipping! We have a very experienced team of people here to help our international customers receive their parts quickly and at very affordable rates!
If you are trying to place an order and our website says that we can not ship to your location please contact us at john@advancedtruckparts.com so that we can give you a custom shipping quote. Once you contact us at john@advancedtruckparts.com we will respond quickly with an accurate shipping quote as long as you provide a full physical address with postal code. In some cases our website may quote and charge you the wrong amount for shipping and if this occurs you will be contacted for additional payment. While we do our best to have our website calculate accurate shipping quotes, in dealing with international shipments this is difficult and sometimes our team has to calculate the correct shipping rate manually.
International customers are responsible for any duties, taxes, custom charges or currency exchange fees that their shipment may incur during transit. In the case of a shipment being refused, all transit charges will be deducted from the customer’s refund.
Damaged Shipments
In the event your product is damaged in transit please contact us at 1-877-795-0656 immediately. All damages must be reported within 24-48 hours of receiving your package. If a shipment arrives at your doorstep and is clearly damaged make sure to take pictures as these will help expedite the return process. All warranty claims and damaged items claims need to be handled through Advanced Truck Parts. Do not contact the manufacturer of the product directly as they will not be able to assist you in receiving a new item. Please do not attempt to install the part as this will void any replacement options or claims.
Refused Shipments
You reserve the right to refuse a shipment should you change your mind and decide to return the product. Please contact us ahead of time if you plan to do this so we can set up the appropriate return information in the system. If a shipment is refused upon delivery, then Advanced Truck Parts will deduct the cost of the return shipping from your refund in addition to the initial shipping charge. If the item is damaged upon arrival or defective then we will take full responsibility for the cost of shipping.
Shipping
We are now shipping internationally! All shipping rates will be calculated, and thus, will vary depending on the shipping location. All shipping rates are calculated based the cost of both the shipping and handling required to send your item.
Once you have placed your order by purchasing an item, it generally takes 1 to 3 business days to process your transaction and get your product on its way to you. The package then spends another 3 to 10 days in transit (or possibly longer in international shipping situations). Thus, you can expect your order to be delivered between 4 to 14 days from when we receive payment for your item.

CATERPILLAR FUEL INJECTORS
Key Points
Caterpillar diesel injectors are engineered for extremely high fuel delivery pressures and precise timing, crucial in Cat’s heavy equipment and truck engines.
Cat pioneered advanced unit injector technology – notably the HEUI (Hydraulic Electronic Unit Injector) introduced in the early 1990s, which uses engine oil hydraulics to intensify fuel pressure for injection.
Faulty injectors in Caterpillar engines often manifest as performance and smoke issues.
A common symptom is excessive black smoke exhaust under load (unburned fuel from a dribbling or stuck-open injector).
Purpose
Caterpillar diesel injectors are engineered for extremely high fuel delivery pressures and precise timing, crucial in Cat’s heavy equipment and truck engines. Cat pioneered advanced unit injector technology – notably the HEUI (Hydraulic Electronic Unit Injector) introduced in the early 1990s, which uses engine oil hydraulics to intensify fuel pressure for injection. Many mid-size Cat engines (3126, C7, C9) employed HEUI to achieve flexible electronic control. In larger truck engines like the C-12, C-15, Caterpillar used mechanically-actuated electronic unit injectors (MEUI), where a cam-driven plunger generates pressure and an electronic solenoid controls timing and fuel metering. These MEUI injectors in engines like the 3406E and C15 ACERT could exceed 20,000 psi injection pressure, enabling fine atomization for better combustion. By providing multiple injection events (pilot/main, etc.) in ACERT engines, Cat injectors help reduce NOx and soot while maintaining the big Cat torque and efficiency. In summary, whether HEUI or MEUI, the injectors are the heart of Cat’s fuel system – delivering the right amount of fuel at precisely the right moment for optimum power, economy, and emissions control.
Common Failure Signs
Faulty injectors in Caterpillar engines often manifest as performance and smoke issues.
A common symptom is excessive black smoke exhaust under load (unburned fuel from a dribbling or stuck-open injector).
At idle or cold start, a bad injector may cause white or gray smoke – indicating fuel is injected but not igniting fully, often accompanied by a miss or rough idle.
The engine might have a pronounced miss/knock on the affected cylinder, especially noticeable in Cat’s unit-injector engines if one injector’s timing or fuel delivery is off.
Power loss and increased fuel consumption will occur as the ECM compensates or if a cylinder isn’t contributing full power.
Electronically controlled Cats (3406E, C7/C9, etc.) will usually trigger a diagnostic code for injector faults – for example, codes for injector solenoid current or balance rates if one injector isn’t performing.
Installation Notes
Installing Caterpillar injectors requires diligence to ensure proper seating and calibration. Always install new copper tip washers and O-rings on each injector – Cat injectors often have multiple O-rings (for fuel, oil, and coolant sealing in some designs) that must be replaced to prevent leaks. Before insertion, coat O-rings lightly with clean oil. When seating the injector in the cylinder head, ensure it is properly aligned; many Cat engines use a hold-down clamping system – torque these screws to spec (e.g. ~55 in·lb followed by 90° turn on some models) as per service manual. Critically, injector trim codes/files must be updated: modern Cat electronic injectors come with a code that tells the ECM the flow characteristics of that injector. After installation on engines like C7, C9, or C15, use Cat ET (Electronic Technician) to enter the new injector’s trim code so the ECM can balance fuel delivery. If the engine is an older mechanical unit injector type (e.g. 3406B), injector timing must be adjusted using the specified gauge tool or timing code – this ensures the injector plunger timing is correctly synchronized with the camshaft. For HEUI systems, make sure to bleed air from the high-pressure oil rail after reassembly (many Cat HEUI engines have a standpipe and rail system that should be primed). Lastly, verify the weep holes on injector seal rings (if any) are unobstructed and the fuel return lines are properly connected. After installation, perform a calibration or cut-out test to confirm each new injector is functioning and that the engine runs smoothly without leaks.

As a fire department, we reached out to Advancedtruckparts.com for some parts. Once we realized their company was in our area, we visited them in person. All of the employees that we came across were very polite and extremely helpful....
Jimmy in parts was exceptional. He went above and beyond to ensure I had the correct part when we needed a new Battery Box lid after ours was stolen! He found the best price possible for the part and made the transaction over the phone quick and easy. Their prices for the same products were lower than the ridiculous prices at dealers services places.
My CPC unit was stolen and I ordered what was the wrong part and quickly order another. I called to return the first part and they caught my mistake and quickly stop payment and refunded my money!!! Excellent customer service and support!!!!
LOOKED UP ON LINE SENT IN INFORMATION TO VERIFY AFTER 530 THINK RESPONCE WOULD BE NEXT MORNING BUT WAS PLEASANTLY SURPRISED THAT I GOT VERIFICATION IN 15 MIN AND PLACED ORDER . GREAT SERVICE !!!!
This is Edward Byrnes with Impressed Mobile Services LLC, I just ordered a brake master cylinder hydro booster combo for my 97 step van, Bob was very helpful and the price very good. Thank you again for the help. PS the song I heard while waiting on hold ( which was not long ) is epic! That is the best “on hold” message I have ever heard.
