Glacier Diesel Power 2010–2018 Dodge Ram 6.7L Cummins Big Line Kit (201011BLK)
Description
Ram made several improvements to the fuel system on the 2010–2018 6.7L Cummins, including a redesigned top-loading fuel filter canister with larger outlet ports. Unfortunately, one restriction still remained—the small factory fuel line and outlet fitting between the fuel filter housing and the CP3 injection pump.
The Glacier Diesel Power Big Line Kit replaces this restrictive section with a full-size 3/8-inch Push-Lok fuel line, custom stainless-steel adapters, and a quick-connect adapter designed specifically for the 2010–2018 fuel filter housing. The result is a cleaner, less restrictive fuel path from the filter housing to the injection pump while replacing the factory pressed-on nylon line with serviceable, high-quality components. The factory line measures approximately 0.190-inch inside diameter, while Glacier's stainless fittings open the passage to approximately 0.300-inch, substantially increasing flow area through the fittings.
Whether your truck is completely stock, equipped with a lift pump, or built for towing and performance, the Big Line Kit is an excellent upgrade that modernizes one of the smallest sections of the factory fuel supply system.
For customers who monitor fuel pressure, an optional billet aluminum sender tee is available, providing a clean and convenient location to install a fuel pressure sender without stacking multiple fittings.
Features
- Fits 2010–2018 Ram 2500, 3500, 4500, and 5500 6.7L Cummins
- Replaces the restrictive factory fuel line between the filter housing and CP3
- Full 3/8-inch Parker Push-Lok fuel hose
- Custom stainless-steel Glacier fuel system adapter
- Glacier quick-connect adapter
- Heavy-duty Push-Lok fitting
- Hose clamps included
- Optional billet aluminum fuel-pressure sender tee
- Serviceable design replaces the factory pressed-on nylon line
- Excellent companion upgrade for stock or aftermarket lift pumps
Why Upgrade Your Fuel System?
Although the 2010+ fuel filter housing was redesigned compared to earlier trucks, the line leaving the housing and feeding the CP3 remained surprisingly small.
Once fuel exits the filter housing, it still travels through a restrictive factory nylon line and small outlet fitting before reaching the injection pump. That narrow section becomes the smallest portion of the supply path regardless of how much fuel the rest of the system can deliver.
The Glacier Big Line Kit removes that bottleneck by replacing the factory line with larger 3/8-inch fuel hose and custom stainless adapters designed specifically for the factory filter housing. This creates a smoother transition to the CP3 while also replacing aging plastic fuel line with durable serviceable components.
For owners installing a lift pump, upgrading the filtration system, or simply refreshing the factory plumbing, this kit helps eliminate one of the remaining restrictions in the fuel supply system.
Glacier Fuel System Tech Tip
Bigger fuel lines do not automatically create more fuel pressure.
Fuel pressure is determined by the entire fuel system, including the lift pump, fuel filters, hose routing, and overall restriction. The purpose of the Big Line Kit is to remove one unnecessary restriction between the filter housing and the CP3—not to guarantee a specific pressure increase.
Monitoring fuel pressure is still one of the best ways to evaluate the health of your lift pump and supply system. The optional billet sender tee makes installing a pressure sender simple while providing accurate pressure readings where they matter most.
Why Glacier Built It This Way
We didn't simply replace the hose—we redesigned the entire connection.
The factory nylon line is permanently attached and not intended for repeated service. Glacier's system replaces that assembly with a serviceable design utilizing premium Parker Push-Lok hose, stainless-steel adapters, and a dedicated quick-connect fitting that interfaces directly with the factory fuel filter housing.
Every fitting was selected to maximize durability while minimizing restriction. Stainless steel offers excellent corrosion resistance and long-term reliability in diesel fuel applications, while Push-Lok hose provides a secure connection without requiring specialty crimping equipment.
The optional billet aluminum sender tee was developed because many owners already monitor fuel pressure. Instead of piecing together generic adapters, Glacier provides a clean, purpose-built solution that integrates seamlessly into the fuel line.
The result is a fuel line upgrade that's easy to install, easy to service, and engineered to complement both stock and performance fuel systems.
Applications
Fits:

- 2012–2018 Ram 4500 6.7L Cummins
- 2012–2018 Ram 5500 6.7L Cummins
Important Notes
- Designed for trucks retaining the factory fuel filter housing.
- Includes the Glacier quick-connect adapter required for 2010–2011 applications.
- Compatible with stock and most aftermarket lift pumps.
- Fuel-pressure sender tee is optional.
- Fuel-pressure sender and gauge are sold separately.
- Verify fitment before ordering.
Common Failure Point
The factory nylon fuel line performs well when new, but after years of heat cycles and engine vibration it becomes another aging component in the fuel system. The pressed-on factory design also makes servicing or replacing the line more difficult than necessary.
Replacing this section with serviceable Push-Lok hose and stainless fittings modernizes one of the last restrictive portions of the factory plumbing while making future maintenance significantly easier.
