The Multiquip 42458 is a genuine OEM Fitting Fuel.312 90 Deg SAE J2044 designed for Whiteman and PRX series ride-on power trowels, including the STX6H, HTX6H, PRX, STXDF, and HTXG6DF. As a direct OEM replacement, this fitting is produced to the same specification as the original part, ensuring a correct, leak-free connection within the fuel circuit. Sourced directly through authorized Multiquip distribution, part 42458 is the right call when you need to restore the fuel system on your trowel to proper working order. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- SAE J2044 Fuel System Compliance: — Manufactured to the SAE J2044 quick-connect fuel fitting standard, ensuring correct sealing performance and material compatibility with modern fuel lines.
- 90-Degree Angled Routing: — The 90-degree bend allows the fuel line to follow the designed routing path within the trowel chassis, maintaining clearance and preventing kinking or chafing.
- Genuine OEM Construction: — Built to Multiquip's original material and dimensional spec, so the fitting seats and seals the same way the factory-installed component does.
- Broad Ride-On Trowel Fitment: — Confirmed for STX6H, HTX6H, PRX, STXDF, and HTXG6DF models, covering both hydrostatic and hybrid ride-on trowel families in the Multiquip lineup.
- Fuel Delivery Integrity: — A damaged or leaking fuel fitting starves the engine of consistent fuel flow and creates a fire hazard; replacing it with part 42458 restores safe, uninterrupted fuel delivery.
- Fuel System Safety: — Proper fuel fittings are a critical safety component — using a correctly rated OEM fitting eliminates the risk of fuel leaks at the connection point during operation.
A fuel fitting is a connector that joins a rigid or flexible fuel line to another component in the engine's fuel delivery circuit. The 90-degree angle on this fitting is intentional — it redirects the fuel line along a specific path engineered into the machine's frame, avoiding heat sources and moving parts. When a fuel fitting cracks, loosens, or its internal seal fails, the result is a fuel leak that can lead to rough running, fuel starvation, or a fire risk. Replacing a worn fitting promptly with the correct OEM part keeps the fuel system sealed and the engine running as intended.
