349-5327 12V Electric Fuel Extraction Pump for Perkins & CAT Diesel Engines
When the fuel transfer pump on your Perkins or Caterpillar engine fails, the machine doesn't run — period. This 12V electric fuel extraction pump is a direct replacement for the 349-5327 OEM unit found on Perkins 800 Series and CAT compact diesel engines. Designed for generators, compact construction equipment, marine auxiliary engines, and industrial power units — anywhere a Perkins 800-series or equivalent CAT engine provides the power.
🔌 12V Electric — Self-Priming: This is an electric fuel pump, not a mechanical lift pump. It requires 12V DC power (typically from the engine's electrical system or a dedicated circuit). Self-priming design eliminates the need for manual bleeding in most installations.
Key Features
Direct OEM Replacement — Engineered as a bolt-on replacement for Perkins 349-5327 and MP10325 fuel transfer pumps. Matches OEM mounting pattern, fuel line connections, and electrical connector specifications.
12V DC Electric Operation — Self-priming electric pump delivers consistent fuel flow regardless of engine RPM — unlike mechanical pumps that lose efficiency at low idle. Critical for generators that run at constant RPM but need reliable starting fuel delivery.
Wide Cross-Reference Coverage — Replaces 349-5327, MP10325, 232-5877, 228-9130, 228-9129, and many more. Compatible with Perkins 804C-33, 804C-33T, 804D-33, 804D-33T, 422E, 432D, 3044C, 259B3, 279C, 279C2, 289C engine models.
Corrosion-Resistant Construction — Aluminum pump body with stainless steel internal components. Designed to withstand the vibration, heat, and fuel chemistry of diesel engine compartments in generator enclosures, engine bays, and machinery frames.
Pre-Set Output Pressure — Factory-calibrated output pressure matches Perkins/CAT fuel system specifications. No regulator adjustment needed for standard installations.

Why This Pump Fails and When to Replace
Electric fuel pumps in industrial and generator applications fail for predictable reasons: (1) Contaminated fuel — running without a properly maintained primary filter allows debris to score the pump's internal surfaces. (2) Water in fuel — causes internal corrosion on the electric motor windings and check valves. (3) Continuous operation — generator pumps that run for thousands of hours between services experience normal brush/motor wear. (4) Voltage issues — low battery voltage or poor ground connections cause the pump motor to overheat. If your engine cranks but won't start, or starts and then dies after a few seconds, test the fuel pump output before replacing injection components.
Frequently Asked Questions
Q: How do I confirm this pump fits my Perkins engine?A: Check your engine's data plate for the model number. If it's an 804C-33, 804C-33T, 804D-33, 804D-33T, 422E, 432D, or 3044C — or a CAT 259B3/279C/279C2/289C — this pump is compatible. Visually compare the mounting flange, fuel line positions, and electrical connector to the product images before ordering.
Q: Is this a mechanical or electric pump?A: This is a 12V electric pump. It requires a 12V DC power supply. It is NOT a mechanical lift pump driven by the engine camshaft. Most Perkins 800-series engines use electric lift pumps — verify your engine's configuration before ordering.
Q: Do I need to bleed the fuel system after installation?A: This pump is self-priming, so in most installations it will draw fuel and purge air on its own. For stubborn air locks (common after a complete system drain), loosen the injection pump inlet fitting until fuel appears, then tighten and attempt to start. Never use starting fluid on a diesel engine.
Q: What causes these pumps to fail — and how do I prevent it?A: Water contamination and dirty fuel are the top two killers. Always maintain your primary fuel filter/water separator. Check for water in the fuel system monthly if the equipment is stored outdoors or runs seasonally. A fuel pressure gauge on the output side can warn you of declining pump performance before it fails completely.
