Glacier Diesel Power 1998.5–2002 Dodge Ram 5.9L Cummins 3/8" Big Line Kit (9852BLK)
Description
The VP44 injection pump depends on a steady supply of clean fuel delivered at the proper pressure. Unfortunately, one of the most restrictive sections of the factory fuel system is the small hard line that connects the fuel filter housing to the injection pump.
The Glacier Diesel Power 3/8" Big Line Kit replaces this restrictive section with a full-size 3/8-inch fuel hose, custom stainless-steel adapters, and heavy-duty Push-Lok fittings to create a smoother, less restrictive path from the fuel filter to the VP44. Whether your truck is stock, equipped with an aftermarket lift pump, or built for towing and performance, this upgrade helps modernize one of the most overlooked portions of the factory fuel system.
The kit is designed to work with the factory fuel filter housing while eliminating the restrictive factory banjo fittings and undersized hard line. Every kit includes premium stainless adapters, Cummins sealing washers, 3/8-inch Push-Lok hose, clamps, 90-degree fittings, and Glacier's billet aluminum sender tee for easy installation of a fuel pressure gauge.
If you're already upgrading your lift pump or refreshing the fuel system on your VP44-powered Cummins, the Big Line Kit is one of the simplest ways to improve serviceability while replacing aging factory plumbing with premium components.

Why Upgrade Your Fuel System?
The VP44 injection pump relies on consistent fuel pressure for both lubrication and cooling. Any unnecessary restriction between the fuel filter housing and the injection pump can make it more difficult for the lift pump to deliver fuel efficiently.
The factory hard line is one of the smallest passages in the fuel supply system. While it works adequately on a stock truck, many owners upgrade this section when installing an aftermarket lift pump or refreshing an aging fuel system.
Replacing the restrictive hard line with a full-size 3/8-inch hose creates a smoother flow path while replacing factory components that have often been exposed to decades of heat cycles, vibration, and diesel fuel.
Glacier Tech Tip
Many VP44 fuel pressure problems are blamed solely on the lift pump, but the entire fuel supply system should be evaluated.
Old hoses, partially restricted fittings, worn banjo bolts, or deteriorated fuel lines can all contribute to unnecessary restriction. Upgrading the plumbing between the filter housing and the VP44 helps eliminate one of the smallest sections of the factory fuel supply path while simplifying future maintenance.
Installing a fuel pressure gauge using the included billet sender tee is one of the best ways to monitor the health of your lift pump and fuel system over time.
Why Glacier Built It This Way
Rather than simply supplying a larger hose, we engineered a complete replacement for the factory restriction.
Our custom stainless-steel adapters eliminate the restrictive factory banjo arrangement while providing durable, corrosion-resistant connections. Premium Push-Lok fittings offer excellent sealing and easy serviceability, and the included billet aluminum sender tee makes adding a fuel pressure sender quick and clean without requiring additional fittings.
The goal wasn't simply to build a bigger line—it was to create a complete fuel line upgrade that installs cleanly, lasts for years, and complements the rest of your fuel system.

Common Failure Point
After more than twenty years of service, many original VP44 trucks still have their factory hard line, banjo fittings, and sealing washers in place. Heat cycles, vibration, and repeated servicing can contribute to leaks or deterioration over time.
Replacing these components during a fuel system upgrade helps eliminate aging plumbing while providing a cleaner, more serviceable fuel supply path.
