Westwood Fuel Pumps
Westwood fuel pumps deliver consistent petrol flow from tanks to carburettors on equipment requiring pressurised fuel delivery. Our fuel pump inventory includes Westwood mower fuel pumps, engine fuel pumps, replacement fuel pumps, and petrol fuel pumps for zero-turn and rider equipment. Westwood Spares stocks Westwood fuel pump assemblies in stock with correct pressure specifications and pulse-operated mechanisms for Briggs & Stratton and Kohler engines, with worldwide shipping on all fuel pump orders. These essential petrol fuel pump components feature diaphragm-operated designs powered by crankcase pressure pulses that overcome fuel height restrictions, ensuring reliable fuel delivery to carburettors regardless of tank position throughout demanding commercial mowing operations.

Frequently Asked Questions
How do I test a Westwood fuel pump?
Test fuel pumps by disconnecting output line, cranking engine whilst observing steady fuel pulses from pump outlet. No fuel flow or weak dribbling indicates pump failure requiring replacement; strong pulses confirm pump function.
How do Westwood fuel pumps work?
Westwood fuel pumps use diaphragms actuated by crankcase pressure pulses through small tubes connected to engine blocks. Alternating pressure and vacuum moves the diaphragm pumping fuel through check valves from tanks to carburettors.
What causes Westwood fuel pump failures?
Fuel pump failures result from torn diaphragms from age or ethanol exposure, failed check valves allowing backflow, clogged pulse tubes preventing diaphragm movement, or contaminated fuel damaging internal components. Replace rather than repair.
Why is there oil in my Westwood fuel pump?
Oil entering fuel pumps indicates overfilled crankcases forcing oil through pulse tubes, or failed crankcase seals allowing oil past pulse port. Drain excess oil, clean pulse tube, and verify proper oil level to prevent recurrence.
Can I bypass a faulty Westwood fuel pump?
Gravity-feed systems with tanks above carburettors can operate without pumps temporarily, but equipment designed with below-tank carburettors requires functional pumps for operation. Install new pumps rather than attempting bypasses.
