Walbro

Walbro is a leading brand for high-performance fuel pumps and related components used in modern petrol engines. This category covers in-tank pump kits, pump-only units, and high-flow competition options designed for 12V DC operation. It includes ITP-series kits, GST/GSS variants, Hi-fuel pumps, and wiring looms or mounting hardware to fit many makes. You’ll find OEM-style replacements as well as race-ready kits that maintain steady fuel pressure under load.

Key features to compare include flow versus pressure, in-tank vs external fitment, and included fittings. Many Walbro options deliver up to 400–510 L/h with pressure up to 8.5 bar, and PWM compatibility for stable high-RPM performance. Look for pre-filters, wiring looms, and cross-reference information to simplify selection.

Typical uses range from boosted street cars to race machines and restorations. When choosing, weigh horsepower targets, fuel type (petrol up to E10 or E85 in some kits), tank space, and inlet/outlet sizes (8/11/22 mm). Some installations require wiring or module changes; others are straightforward replacements.

Variations include GST400HR high-rate in-tank kits, ITP/ITP-series kits, Hi-In-Tank units, and FP604-15 out-tank pumps, plus filters such as 22-190 and 22-450. For fitment, consult Injection Pump Application lists and cross-reference guides. For installation parts, see The Green Spark Plug Company.
