In-Tank Fuel Pumps

In-Tank Fuel Pumps are compact, self-contained units housed inside the fuel tank to deliver fuel directly to the engine. This category includes pump modules, complete in-tank pump kits, and related accessories such as pre-filters, sleeves, and mounting hardware. Most units are 12V DC, designed for quiet operation and easy installation, offering reliable priming, stable pressure, and reduced heat/load on the rest of the fuel system for both daily drivers and performance applications.

Product variety ranges from standard drop-in pumps and pump kits (ITP004, ITP085, ITP105, ITP121) to high-performance and competition units (ITP244, GST450) and SPI-style pumps (GSS278/279). Flow rates commonly span 120–318 L/hr with working pressures from about 3 to 8 bar, depending on the model. Accessories like pre-filters (22-135, 22-169, 22-770) and slim sleeves (22-332) protect the pump and keep fuel delivery steady. Kits differ from pump-only modules but both aim for reliable fuel supply in tight spaces.

Key buying considerations include vehicle compatibility, horsepower targets, required fuel pressure, tank space, and inlet/outlet fittings (typical 6–11 mm). Ethanol compatibility (E10–E85), PWM capability, and whether you need a full kit or a pump-only module should guide your choice. Always consult cross-reference application guides to ensure fitment, and source from reputable suppliers for durable, ready-to-install in-tank fuel pumps, such as The Green Spark Plug Company.
