Frequently Asked Questions
Q: What are the symptoms of a failing fuel transfer pump on CAT 3304 or 3306 engines?
A: Common symptoms include engine stalling or hesitation under load, difficulty starting (especially when hot), reduced engine power, worsening fuel economy, and visible fuel leakage around the pump housing. The 3304 and 3306 are often used in generators, pumps, and heavy equipment — fuel delivery issues will cause these to lose power or shut down unexpectedly.
Q: Where is the 1W1695 fuel transfer pump located on a CAT 3304 or 3306 engine?
A: The fuel transfer pump is typically mounted on the engine block, driven by the engine's camshaft or gear train. On 3304 and 3306 engines, it is usually located on the left-hand side of the block. Access may require removing protective covers or adjacent components. Refer to your engine service manual for the exact location.
Q: Does the 1W1695 fit both the CAT 3304 and 3306 engines?
A: Yes, the 1W1695 (1W-1695) fuel transfer pump is designed as a direct OEM-compatible replacement for both the CAT 3304 and 3306 diesel engines. Both engines share the same fuel system architecture. If you are unsure about your engine model, contact us with your engine serial number for confirmation.
Q: Should I change the fuel filter when replacing the fuel transfer pump?
A: Absolutely. A clogged fuel filter can cause fuel pump failure by forcing the pump to work harder and overheat. Always replace the fuel filter when installing a new fuel transfer pump, and inspect fuel lines for cracks, leaks, or contamination that could damage the new pump.
Q: What fuel types are compatible with this fuel transfer pump?
A: The 1W1695 fuel transfer pump is designed for diesel fuel used in CAT 3304 and 3306 diesel engines. Do not use with gasoline, biodiesel blends above B20, or alternative fuels unless specifically confirmed — doing so may damage pump seals and internal components.
Q: Can I install this fuel transfer pump myself?
A: Installation requires basic mechanical skills and standard hand tools. The pump is bolt-on with a gasket seal. However, proper installation requires cleaning the mounting surface, using a new gasket, and bleeding the fuel system after installation. If you are not confident, have a qualified technician perform the installation.
Q: How do I confirm this is the correct fuel pump for my engine?
A: Check the part number on your current fuel transfer pump — if it reads 1W1695 or 1W-1695, this is the correct replacement. Alternatively, provide us with your CAT 3304 or 3306 engine serial number and we will verify compatibility before you order.
Q: What is the warranty on this fuel transfer pump?
A: This fuel transfer pump comes with a 12-month warranty covering manufacturing defects. The warranty does not cover damage caused by contaminated fuel, improper installation, or using incorrect fuel types.
