Yezoauto Fuel Pump With Regulator And Tank Seal
The Yezoauto unit fits Mercury Marine Mercruiser 4-Stroke Outboard models from 2002 through 2010, covering 20HP to 60HP. Interchange parts include OE# 892267A51 and related numbers. Functionally, the fuel pump supplies clean pressurized fuel to injectors and informs the fuel level to the instrument cluster. It also supports fuel nozzle shut-off during refueling and other critical system functions.
Best for: Mercruiser owners seeking a direct replacement that includes a regulator and gasket/tank seal. This is a solid choice for standard EFI outboards in the specified range. Better for: boats needing a straightforward, OEM-style upgrade without custom tuning. Caution: verify exact engine year compatibility—some models may require additional adapters.
JLM MARINE 14360A78 Fuel Pump for Mercury Mariner
This replacement is designed for Mercury Mariner models in a wide HP range, including 30-300 HP outboards and various configurations. It covers multiple Mercury 2-stroke and 3-stroke variants and is described as suitable for both electrical and manual fuel pump setups. It’s particularly suitable for boaters who need a single part that spans several Mercury configurations.
Best for: owners looking for a broad-coverage replacement that can handle diverse Mercury Mariner engines. Why selected: versatility across many Mercury families reduces parts stocking. Caution: consult product description for exact model mapping, as some listings emphasize compatibility with broader ranges rather than a fixed match for every engine.
Yezoauto EFI Fuel Pump for Mercury Mariner 150-250 HP
Designed for Mercury Mariner Outboard engines ranging from 150 to 250 HP (1993–2002). It lists multiple interchange numbers including OE# 809088T-1 and 809088T1. Functionally, it delivers clean, pressurized fuel to the EFI system and contributes to accurate fuel level readings and safe refueling operations. This is a good fit for high-output engines that require a consistent high-pressure fuel supply.
Best for: high-horsepower outboards that rely on EFI for performance. Choose this if you need a pump built for higher fuel demands. Caution: ensure the specific HP and year range match your engine; incorrect fit can affect fuel pressure and reliability.
SeaSierra Boat Marine 899106T01 Fuel Pump
The SeaSierra 899106T01 unit targets Mercury 30-60 HP outboards and replaces internal Mercury components, including OEM numbers such as 881862T and 892874T01. It is positioned as a replacement for internal fuel system components within Mercury 4-stroke engines, offering compatibility with a range of 30-60 HP models.
Best for: owners with mid-range Mercury outboards needing a direct internal component replacement. Limitation: availability may vary by model year; verify the exact Mercury part numbers match your engine before purchase.
Yezoauto Fuel Pump for Mercury Marine Mercruiser 2002-2010 / Honda EFI
This Yezoauto pump covers a broad Mercruiser 4-stroke range (2002-2010) and includes compatibility with Honda EFI applications. Interchange parts list includes OE# 892267A51, 898101T67, and 892267530, among others. Functionally, it performs essential fuel delivery to EFI injectors and provides fuel level data to gauges, while also supporting safe refueling operations.
Best for: buyers seeking broad compatibility across Mercruiser and Honda EFI-equipped engines. Choose this if you want a single part that spans multiple brands within the EFI ecosystem. Caution: confirm OE numbers precisely to avoid a mismatch with your engine’s fuel rail configuration.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Match the HP range, model family (Mercury Mercruiser, Mariner, Honda EFI), and year to avoid mismatches.
- Interchange parts: Check OE numbers listed with each pump; accurate interchange ensures proper fit and function.
- Fuel system type: Confirm whether your engine uses a high-pressure EFI system or a lower-pressure priming pump to select the correct unit.
- Regulator and seals: Some pumps include regulators and tank seals; these accessories simplify installation and help prevent leaks.
- Materials and corrosion resistance: Marine fuels can be aggressive; select pumps described as ethanol-resistant or designed for marine use.
- Installation scope: Consider whether the pump needs custom brackets, lines, or electrical adapters, especially for cross-brand compatibility.
- Warranty and return policy: Marine parts often require precise fit; check return terms if the part doesn’t match.
