Fuel Lines & Rails

When it comes to fuel, Chevrolet’s LB7 Duramax powered truck is a demanding machine — but you can maximize efficiency by ensuring its 6.6 liter engine is being supplied with all of the fuel it needs. If your LB7s fuel lines need replacing, consider purchasing an LB7 fuel line kit that contains all of the parts you need to replace your truck’s LB7 fuel supply lines entirely.

You can also get replacement parts that can solve issues with your LB7 fuel rail pressure sensor and LB7 fuel injector lines. If your truck is having trouble with its fuel system, it may not be the LB7 fuel lines, fuel supply lines or LB7 injector lines that are at fault. Instead, the Duramax’s fuel rail pressure sensor could be malfunctioning.

The fuel rail pressure sensor is not a part you can easily disassemble and fix. If the sensor is causing issues a Duramax fuel rail pressure sensor replacement is the best option.
