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!

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.

MACK FUEL INJECTORS
Key Points
Mack trucks utilize fuel injectors to ensure their diesel engines produce the hallmark “Bulldog” torque with efficiency.
Up until the early 2000s, Mack’s engines (E7, E-Tech series) used a Unit Pump fuel system: each cylinder had a dedicated Bosch pump plunger (unit pump) feeding a short fuel line to a nozzle in the head.
A failing injector in a Mack engine will produce symptoms much like those in Volvos (given the shared technology), with some differences in older engines.
In an E7 E-Tech with unit pumps, one cylinder not getting fuel will cause a notable miss (rough idle and less power) and often white smoke from that cylinder’s unburnt fuel.
Purpose
Mack trucks utilize fuel injectors to ensure their diesel engines produce the hallmark “Bulldog” torque with efficiency. Up until the early 2000s, Mack’s engines (E7, E-Tech series) used a Unit Pump fuel system: each cylinder had a dedicated Bosch pump plunger (unit pump) feeding a short fuel line to a nozzle in the head. This system, similar in concept to unit injectors, allowed very high injection pressure and electronic control (Electronic Unit Pump, EUP) while simplifying service – a faulty pump could be swapped individually. The unit pump system delivered reliable performance and was an early Mack approach to meet emissions without a single injection pump. In later engines (MP7, MP8 – after Mack’s integration with Volvo), Mack adopted high-pressure common rail injection like Volvo’s, or in some cases electronic unit injectors, to achieve finer control. The current Mack MP8, for example, is essentially a Volvo D13 engine and uses a common rail capable of multiple injections per stroke for clean combustion. Thus, whether in the older mechanical unit-pump engines or newer common-rail ones, Mack injectors serve to inject the exact fuel amount at the exact right time, giving Mack engines strong power and better fuel economy while adhering to emissions standards.
Common Failure Signs
A failing injector in a Mack engine will produce symptoms much like those in Volvos (given the shared technology), with some differences in older engines.
In an E7 E-Tech with unit pumps, one cylinder not getting fuel will cause a notable miss (rough idle and less power) and often white smoke from that cylinder’s unburnt fuel.
Because each pump/nozzle is separate, a single-cylinder misfire is more pronounced – mechanics often crack each injector line to find which cylinder isn’t contributing.
Black smoke under load indicates one or more injectors are over-fueling or not atomizing well, common if a nozzle tip is eroded.
In the later MP8 common-rail engines, symptoms include hard starting or long crank (if an injector leaks internally, rail pressure may not build to enable start), rough idle, and excessive smoke (white smoke when cold if an injector dribbles, black smoke when accelerating if fueling is uneven).
The dashboard may illuminate a check engine light; the ECU will flag cylinder imbalance or rail pressure deviations if an injector sticks or leaks.
Installation Notes
When installing injectors in a Mack engine, the procedure depends on the fuel system type. For the unit pump (EUP) engines (E7/E-Tech), each injector assembly comprises a separate pump and nozzle. Replacing the pump element (mounted in block) or the injector nozzle in the head requires re-timing and bleeding. If a unit pump is replaced, ensure the cam is on base circle for that pump lobe before installation; torque the pump retaining bolts evenly. The injector nozzles in the head have copper washers that must be renewed and usually require a slide hammer to pull the old ones. It’s crucial to bleed air after installation: on unit pump systems, crank the engine with fuel shutoff or use the hand primer to purge air from replaced components, otherwise hard starting will occur. For common rail Mack engines (MP7/MP8), the injector installation mirrors Volvo’s: always use new sealing washers on the injector tip, replace injector sleeves if removed, and torque the injector hold-down clamp properly. Connect each injector’s electrical plug securely (Mack/Volvo units use a sealed connector per injector under the valve cover). Because MP8 uses a shared rail, replace the high-pressure fuel lines to each injector once removed, and torque the line fittings with a crow-foot wrench to the specified value to prevent leaks. After installation, program any injector calibration codes into the ECU via Mack’s VCADS/Tech Tool (newer common-rail injectors often have codes like Volvo’s). It’s advisable to carry out an injector cut-out test once the engine is running to verify each new injector is functioning – the engine ECM can cut fuel to each cylinder in turn to identify any anomaly. Finally, check for fuel leaks at the feed lines and ensure no check engine light or rail pressure code remains active. Following these steps will ensure the new injectors deliver the expected Mack performance.
Important:
Always verify fitment by part number before installation and follow OEM torque specifications.Important Notice:

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.
