Grade C Head Gaskets, valve cover gaskets, intake & exhaust gaskets are available when you need to remove and reinstall the cylinder heads on your truck. A wide variety of other gaskets are offered such as front and rear main seals that are known to leak over time.

Fuel Injector Lines

ACDelco offers fuel injector lines, return lines, the rail-to-rail crossover line as well as the line from the CP4 injection pump to the rail. The Injection Lines are sold individually and feed the injector with fuel from the high-pressure rail. One injection line works for two cylinders, such as the fuel line that works on cylinder 1 also works on cylinder 8. The fuel line that works on cylinder 2 also works on cylinder 7, cylinder 3 also works on cylinder 6, and cylinder 4 also works on cylinder 5. These high-quality lines are manufactured to provide long service life.
 

Sensors

Replace the failed sensor on your Duramax with an ACDelco unit and ensure it runs as the factory intended. The GM Water-In-Filter (WIF) sensor is a crucial part of the stock fuel system that alerts the driver that there is water in the fuel. Water can cause catastrophic damage to the engine if it goes unchecked, so it is important to replace the WIF when necessary. Other harnesses and sensors are available to help keep your truck on the road such as the inner injector harness and oil pressure sensor.
 
GM and ACDelco powertrain and maintenance parts provide you with the same fit and function as the day your truck rolled off the assembly line. When it’s time for routine maintenance on your Duramax diesel, XDP has you covered with the ACDelco OEM filters you need. Keep your Chevrolet Silverado or GMC Sierra running its best with all the Genuine GM & AC Delco Parts available at XDP.
