High-Flow 340 LPH In-Tank Pump for LS & LT Builds

Achieve consistent fuel pressure and slosh control in your LS or LT build with an integrated baffle and fuel bladder that ensures uninterrupted flow during hard launches and cornering. The 340 LPH assembly installs directly in the tank for quick engine or induction upgrades without replacing the pump and supports both EFI and carbureted setups for versatile performance.

DIY In-Tank 340 LPH Fuel Pump Kit for LS and LT Swaps

When swapping in an LS or LT powerplant, maintaining stable fuel pressure is crucial and the DIY in-Tank Fuel Pump Kit-340 LPH is built to deliver a constant 340 liters per hour directly from the tank. Its integrated baffle with a fuel bladder keeps every drop at the pickup during hard launches and tight cornering. The complete kit includes hanger and lock ring assemblies plus a precise drill guide for a straightforward installation process.

Advanced Fuel Bladder Baffle for Uninterrupted Supply

This kit's integrated baffle with a fuel bladder is engineered to keep gasoline pooled at the pump inlet, even during aggressive cornering or rapid acceleration. By trapping fuel around the pickup, it eliminates the air gaps that can cause momentary lean conditions and engine hesitation. Racers and daily drivers alike benefit from consistent flow, as the bladder compensates for slosh and tank movement without the need for external surge tanks. This internal solution ensures that every drop of fuel is available when the demand spikes.

340 LPH Output Supporting LS and LT Engine Demands

Rated at 340 liters per hour, this pump delivers the volume required by high-displacement LS and LT engines running both fuel injection and carburetion. Its robust flow capacity provides ample headroom for future power upgrades such as forced induction or nitrous systems, so you won't have to replace the pump when power levels climb. Consistent pressure under load means throttle response remains sharp and combustion stays optimal throughout the rev range. It's a versatile choice for anyone looking to maximize output without compromising reliability.

Comprehensive Kit Design Simplifies In Tank Conversion

Every component needed for a clean retrofit is included: a precision hanger assembly, leak-proof lock ring, and a drill guide that guarantees hole alignment before cutting into the tank. Clear, step-by-step instructions walk you through each stage, reducing installation time and avoiding common pitfalls. By integrating all hardware into one package, the kit transforms a daunting in tank modification into a straightforward task for both seasoned mechanics and first-time DIYers. The result is a secure, leak-free setup that matches factory reliability.

Corrosion-Resistant Materials for Enduring Reliability

Critical parts are crafted from stainless steel and aircraft-grade aluminum, delivering exceptional resistance to ethanol-blended fuels and road contaminants. Durable polymer components within the pump and hanger assembly resist warping and chemical breakdown, ensuring tight seals year after year. This attention to material selection minimizes maintenance and replacement costs over the long term, even in extreme environments. Proudly manufactured in the USA, the assembly meets stringent quality standards for both fit and finish.

Engineered for reliable flow in LS LT swaps. To explore a smaller capacity fuel pump kit at 200 LPH consider our DIY in-Tank Fuel Pump Kit-200 LPH.
