WOD LS Swap Fuel Plumbing Kits | Simplifying LS Fuel Systems

LS Fuel Rails Made Simple

Factory-style returnless LS fuel rails work extremely well when paired with the correct fuel system components. The WOD non-return plumbing kit was specifically engineered around:

• GM LS returnless fuel rails
• stable fuel pressure delivery
• simplified installation
• naturally aspirated and moderate performance LS combinations

By regulating pressure at the rear instead of the engine bay, it eliminates the need to run a dedicated return line all the way forward and back.

That dramatically simplifies plumbing on:

• rear-engine buggies
• mid-engine chassis
• custom LS swaps
• Ultra4 cars
• compact rock crawler builds

while still maintaining consistent fuel delivery.

Reliable LS Swap Fuel Pump Setup

At the heart of the system is a proven Walbro 255 LPH fuel pump. The Walbro pump has become one of the most trusted LS swap fuel pump solutions because of its:

• reliability
• consistent pressure
• compact size
• off-road durability
• broad aftermarket support

The 255 LPH flow capacity works extremely well for:

• naturally aspirated LS engines
• moderate horsepower applications
• trail rigs
• crawlers
• race buggies

while still maintaining stable fuel pressure under aggressive off-road conditions. Combined with premium Fragola -6 AN hose and fittings, the result is a hard core fuel system that can survive the trails:

• vibration
• hard impacts
• suspension movement
• race conditions
• trail abuse

without constantly needing repairs or adjustments.
