Feiya Machinery is a trusted manufacturer of high-performance components for the global petroleum equipment industry. We specialize in producing critical Fuel Dispenser Parts through advanced aluminum die casting and precision CNC machining. Whether you are a dispenser assembler or a service provider for petrol stations, we supply the rugged, explosion-proof hardware needed to keep fuel flowing safely and accurately.
Our product portfolio covers the entire fluid path, including automatic nozzles, fuel swivels, breakaways, flow meter bodies, and vapor recovery components. Unlike generic suppliers, Feiya controls the entire production cycle in-house. We utilize high-density aluminum alloys (ADC12) to resist corrosion from gasoline and diesel, and employ strict leak testing protocols on every unit. From casting the raw housing to the final machining of sealing surfaces, we ensure our parts meet the rigorous demands of heavy-duty fueling environments.

Fueling environments are harsh. Components must withstand constant chemical exposure, high pressures, and physical abuse. Feiya applies rigorous manufacturing standards to ensure that the parts of a fuel dispenser we produce—from nozzle bodies to flow meter housings—deliver long-term reliability and safety.
Global markets require different specifications. What works in Europe might not fit the standards in Southeast Asia. Feiya provides flexible OEM customization services to help you adapt. Whether you are developing a new line of proprietary gas pump dispenser models or need a rugged replacement part for legacy equipment, our engineering team is ready. We support Private Labeling, Reverse Engineering, and structural modifications, turning your technical concepts into mass-produced aluminum reality.
Customization Capabilities Table:
| Customization Service | Feiya OEM Technical Solutions |
| Private Labeling (Branding) | Brand Visibility:We can cast your company logo directly into the aluminum body of nozzles or swivels. This "Cast-in" branding is permanent and impossible to remove, protecting your market identity and preventing counterfeiting. |
| Connection Standards | Thread Adaptation: A gas pump dispenser in the US uses NPT threads, while Europe uses BSPP. We customize the CNC machining of inlet/outlet ports to ensure your parts (swivels, breakaways) perfectly match the local installation standards of your target market. |

| Material Upgrades | Plastic-to-Aluminum: Many cheaper dispensers use plastic internal valves that crack over time. We can reverse-engineer these failures and create durable Aluminum Die Cast replacements, offering a "Heavy-Duty" upgrade kit for your maintenance customers. |
| Flow Rate Tuning | Internal Geometry: For high-speed diesel applications (truck stops), we can modify the internal flow path of the nozzle body or meter housing to reduce turbulence and increase gallons-per-minute (GPM) throughput without changing the external dimensions. |
| Cold Weather Spec | Seal Selection: For gas pump dispenser units operating in freezing climates (e.g., Russia, Canada), we customize the assembly with Low-Temp Fluorosilicone seals to prevent leakage and stiffness at -40°C. |
Manufacturing hardware for the petroleum industry requires zero tolerance for error. A microscopic crack can lead to a hazardous fuel leak. At Feiya, we employ a strict, multi-stage production protocol to ensure that all gas pump parts leaving our factory—whether nozzles, swivels, or meter bodies—are safe, durable, and ready for the field.

Feiya is a seasoned OEM manufacturer with 17 years of expertise in aluminum die casting. While renowned for our multi-platform motorcycle cylinder heads, our capabilities extend to automotive structural parts and precision fuel dispenser components. We provide complete end-to-end support—from mold development and high/low-pressure die casting to complex CNC machining and rigorous testing—delivering ready-to-assemble solutions for diverse industries.
Operating within a 17,000+ m² facility, Feiya integrates the complete aluminum manufacturing cycle—from in-house mold design and die casting (HPDC & LPDC) to precision CNC machining. Equipped with over 30 advanced casting units and 125+ CNC centers, we maintain an annual capacity exceeding 5,000 tons. This vertical integration allows us to strictly control production timelines and guarantee stable, scalable supply for your critical OEM projects.
Quality is the core of our operations. Feiya is ISO 9001 certified and recognized as a National High-Tech Enterprise and a Technology-Based SME in Zhejiang. We adhere to rigorous quality management systems to monitor every process, from raw material inspection to final tolerance checks. These credentials reflect our commitment to technical innovation and prove our reliability as a trusted partner for global automotive and industrial clients.
The "gas pump keeps clicking" off prematurely is a common frustration caused by a sensitive or poorly machined sensing port. Feiya uses precise CNC machining for the automatic shut-off nozzle mechanism. We calibrate the Venturi port sensitivity to ensure the nozzle only shuts off when the fuel level actually reaches the tip, ensuring a smooth fueling experience without false stops.

Yes. A gas pump hose leaking at the connection point is usually due to worn O-rings in the swivel. Our fuel pump swivels feature a dual-plane rotation design with high-grade Viton seals. This allows the hose to move freely without twisting or binding, reducing stress on the gaskets and maintaining a leak-proof seal for years, even in high-traffic stations.
A gas pump breakaway is a critical safety device designed to separate if a car drives off with the nozzle still in the tank. It instantly seals the fuel flow to prevent a massive spill. At Feiya, we perform pull-force testing on every batch of breakaways to ensure they separate at the exact specified tension (e.g., 300 lbs), guaranteeing reliable drive-off protection.
A slow gas pump is often caused by high internal resistance or clogged filters. Feiya manufactures fuel flow meter bodies with optimized internal channels to minimize pressure drop. While we recommend checking the dispenser filter first, upgrading to our precision-cast aluminum meter bodies ensures maximum flow efficiency and accurate metering without restricting the pump's performance.
How does a nozzle know when the tank is full without electronics? It relies on the Venturi effect.
· The Mechanism: As fuel flows through the nozzle, it creates a vacuum at the sensing port (a tiny hole near the tip). Air is drawn in through this port.
· The Trigger: When fuel covers the port, the airflow stops, causing an instant vacuum spike inside the nozzle diaphragm. This mechanical pressure change trips the latch and shuts off the flow.
· Our Precision: Feiya precisely machines this sensing port to exact diameters. If it's too large, the nozzle won't shut off (spill risk); if too small, it clicks off early (pre-mature shut-off). Our precision ensures the perfect balance.
Modern environmental regulations require capturing gasoline fumes. This is known as Stage II Vapor Recovery.
· The Challenge: The system must suck vapors back into the underground tank while pumping fuel out. This requires coaxial hoses and specialized nozzle vapor paths.
· The Casting Role: The internal casting of the vapor recovery nozzle must be airtight with smooth channels to prevent liquid blockage in the vapor path. Feiya’s vacuum die casting minimizes internal turbulence, ensuring maximum vapor capture rates to meet strict EPA and European environmental standards.
Most fuel dispensers use a positive displacement meter to measure volume. This device uses pistons or gears to physically move a fixed amount of liquid with each rotation.
· Wear & Drift: Over time, grit in the fuel can wear down the aluminum housing, causing fuel to bypass the pistons ("meter drift"), leading to financial loss.
· Hardness Solution: Feiya uses hard-anodized aluminum for our meter bodies. This surface treatment increases the hardness (Rockwell C scale) of the cylinder walls, resisting abrasion and ensuring the flow meter calibration remains accurate over millions of gallons.
Fuel flowing at high velocity generates static electricity. If not grounded, a spark can cause an explosion.
· The Danger of Plastic: Cheap plastic components act as insulators, allowing charge to build up.
· The Aluminum Advantage: All metallic components of a fuel dispenser manufactured by Feiya act as conductors. We ensure electrical continuity from the nozzle tip, through the swivel, to the ground wire. This continuous path safely dissipates electrostatic discharge (ESD), providing a critical layer of passive safety for the fueling station.
