DeatschWerks DW255 In-Tank Fuel Pump – 1989-1994 Nissan 240SX (S13) | 255 lph with Setup Kit

Upgrade your S13 240SX’s fuel delivery with the DeatschWerks DW255 In-Tank Fuel Pump — a 255 lph high-flow in-tank fuel pump bundled with the 1989–1994 Nissan 240SX platform-specific setup kit for a complete, direct drop-in installation. DeatschWerks’ DW255 delivers the fuel flow headroom needed for modified KA24DE builds, SR20DET swaps, and any S13 application where the factory pump is limiting fuel delivery. The included setup kit provides all the platform-specific hardware needed to install the DW255 directly into the factory S13 fuel pump assembly — no fabrication, no universal adapters, no guesswork.

Key Features:

• 255 lph flow rate — high-flow fuel pump capable of supporting significantly more power than the factory S13 pump
• 1989–1994 Nissan 240SX (S13) setup kit included — platform-specific hardware for direct drop-in installation into the factory fuel pump assembly
• In-tank design — installs in the factory fuel tank location for a clean, OEM-style installation
• DeatschWerks DW255 — proven high-flow pump from one of the most trusted names in performance fuel system components
• Supports engine swaps — 255 lph capacity supports SR20DET, KA24DE, and other common S13 engine configurations at elevated power levels
• Complete kit — pump and setup kit bundled together for a single-purchase installation solution

Performance Benefits:

• 255 lph Flow Capacity: Delivers significantly more fuel than the factory S13 pump, supporting higher injector duty cycles and increased fuel demand at elevated power levels without fuel pressure drop
• Consistent Fuel Pressure: High-flow pump maintains consistent fuel pressure under the sustained high-demand conditions of performance driving and track use — preventing the lean conditions and power loss caused by an inadequate factory pump
• SR20DET Swap Support: 255 lph capacity is well-suited for turbocharged SR20DET builds running upgraded injectors at moderate to high boost levels
• KA24DE Performance Support: Supports modified KA24DE builds running larger injectors and increased fuel demand from forced induction or high-compression naturally aspirated builds
• Platform-Specific Setup Kit: Eliminates the fitment uncertainty of universal pump kits — the S13-specific setup kit ensures correct installation dimensions, wiring connections, and pump orientation for the factory fuel pump assembly

• DeatschWerks DW255 in-tank fuel pump
• 1989–1994 Nissan 240SX (S13) platform-specific setup kit
• Installation instructions

Installation Notes:

• Professional installation recommended — fuel system work involves flammable fuel and pressurized lines
• Depressurize the fuel system before beginning installation
• Disconnect the battery before working on the fuel system
• Replace the fuel filter at the same time as the fuel pump for best results
• Inspect the fuel pump sock/strainer and replace if clogged or damaged
• Verify fuel pressure after installation with a fuel pressure gauge before starting the engine
• Check for fuel leaks after installation before returning the vehicle to service
• ECU tune required if upgrading injector size simultaneously

DW255 vs. Factory S13 Fuel Pump:

The factory Nissan 240SX (S13) fuel pump is rated for the stock KA24DE’s fuel demands — adequate for a stock engine but insufficient for modified builds running larger injectors, higher boost, or engine swaps with greater fuel requirements. As fuel pump flow capacity is exceeded, fuel pressure drops under high-demand conditions — causing lean air/fuel ratios that reduce power and, in severe cases, cause engine damage. The DeatschWerks DW255 provides 255 lph of flow capacity, delivering the headroom needed to support modified S13 builds reliably. The included S13-specific setup kit eliminates the fitment uncertainty of universal pump installations, ensuring the DW255 drops directly into the factory fuel pump assembly without modification.

The S13 240SX Platform:

The 1989–1994 Nissan 240SX (S13) is one of the most popular and versatile Japanese sports car platforms in the enthusiast community — a lightweight, rear-wheel-drive chassis that has become a staple of drifting, time attack, and grassroots motorsport. The S13’s popularity as an SR20DET swap platform makes fuel system upgrades particularly important — the turbocharged SR20DET’s fuel demands at elevated boost levels quickly exceed the factory KA24DE fuel pump’s capacity. The DeatschWerks DW255 with S13 setup kit is one of the most straightforward and reliable fuel pump upgrade solutions available for the platform.

Why DeatschWerks?

DeatschWerks has been producing high-performance fuel system components since 2004, with a comprehensive lineup of fuel pumps, injectors, fuel rails, surge tanks, and fuel system accessories covering over 800 SKUs across sport compact, muscle, European, and powersport applications. Their DW255 in-tank pump is one of their most popular products — a proven, reliable high-flow pump trusted by performance builders worldwide. DeatschWerks’ platform-specific setup kits eliminate the guesswork of universal fuel pump installations, ensuring correct fitment and reliable operation from the first start.

Perfect For:

• 1989–1994 Nissan 240SX (S13) builds running SR20DET swaps at moderate to high boost levels
• Modified KA24DE builds running larger injectors and increased fuel demand
• Any S13 build where the factory fuel pump is limiting fuel delivery capacity
• S13 owners replacing a worn or failing factory fuel pump with a high-flow upgrade
• Anyone building a reliable, performance-focused S13 who wants DeatschWerks’ proven pump quality with a platform-specific setup kit

Pro Tip: Replace the fuel filter and fuel pump sock/strainer at the same time as the pump. A clogged filter or strainer restricts flow to the new pump and prevents it from delivering its rated 255 lph — defeating the purpose of the upgrade. Fresh filter + fresh strainer + new pump = a complete, reliable fuel delivery foundation.

Note: S13 (1989–1994) fitment only — not for the S14 240SX (1995–1998). ECU tune required if upgrading injector size simultaneously. Always verify fuel system connections are leak-free and fuel pressure is correct before driving the vehicle.
