340 LPH Pump with Integrated Baffle for LS and LT Tanks

Maintaining your LS or LT powertrain's fuel supply under extreme conditions, the DIY in-Tank Fuel Pump Kit 340 LPH pairs a precision engineered baffle and integrated fuel bladder to deliver 340 LPH of consistent flow. Complete with prewired connections and all mounting hardware for EFI and carbureted systems, it installs directly in the tank to eliminate pump swaps when upgrading engines or induction and controls slosh during hard launches, cornering, and braking.

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

When an LS or LT engine finds its home in a classic frame, uninterrupted fuel delivery under load becomes a top priority and the DIY in Tank Fuel Pump Kit 340 LPH supplies 340 liters per hour to keep the pump primed. Featuring an internal baffle and a fuel bladder it traps fuel at the pickup during hard launches and tight turns to prevent air slugs and lean spots. Installation is made straightforward by the included hanger, lock ring assembly and precision drill guide which ensure proper tank opening alignment. Drivers running EFI or carbureted setups gain a self contained solution that supports future induction upgrades without a pump swap.

Advanced Baffle with Integrated Fuel Bladder Ensuring Consistent Pickup

The built-in baffle features a fuel bladder that traps liquid around the inlet even during aggressive cornering, rapid acceleration, and sudden braking. By maintaining a pocket of fuel at the pump pickup, it eliminates air ingestion that can cause lean spots and hesitation under load. This internal solution removes the need for an external surge tank while delivering uninterrupted flow when demand spikes. Whether on the street or the track, drivers benefit from stable pressure for crisp throttle response.

340 LPH Flow Rate Offering Room for Engine and Induction Growth

Delivering 340 liters per hour inside the tank, this pump meets the demands of LS and LT engines running fuel injection or a carburetor setup. The generous flow rate accommodates future upgrades such as forced induction or nitrous oxide without requiring a pump swap. Maintaining consistent volume under load preserves optimal combustion and power delivery across the rev range. Builders planning horsepower increases gain confidence knowing their fuel system has built-in headroom.

Complete Kit Components Simplifying Tank Modification

Every part needed for an in-tank installation is included in one package: a hanger assembly, lock ring assembly, precision drill guide, and detailed instructions. The drill guide ensures perfect hole placement before cutting, while the hanger and lock ring seal securely to prevent leaks. Step-by-step directions lead both seasoned technicians and first-time installers through each phase of the modification. Combining hardware and guidance in a single kit transforms a complex retrofit into a straightforward project.

Corrosion Resistant Hardware for Reliable Performance

Key components are crafted from stainless steel and aluminum that resist ethanol-blended fuels and road contaminants over time. Polymer fittings and seals maintain their shape under heat and chemical exposure, preventing warping or breakdown. These durable material choices extend service intervals and reduce the need for premature replacements. The result is a fuel assembly built to withstand daily commuting and demanding track duty without compromise.

You can trust its reliable performance under stress. To complete your fuel system upgrade with a smaller capacity fuel pump Kit at 200 LPH consider our DIY in-Tank Fuel Pump Kit-200 LPH.
