Yeoflagtrade Low-Pressure Marine Fuel Pump for Volvo Penta/Mercruiser 1994–1998 — Direct-Fit, Carbureted V6/V8 Replacement

Yeoflagtrade’s low-pressure marine fuel pump is a direct-fit replacement for many 1994–1998 Volvo Penta and Mercruiser carbureted outboard/stern drive engines, restoring reliable fuel delivery for single-pump systems.

This aftermarket replacement fuel pump is made to match the fit and function of common original equipment used on carbureted V6 and V8 marine engines from the mid‑1990s. It replaces a number of OE part numbers (including Sierra 18-7326 and several OMC/Volvo Penta references) and fits low-pressure configurations that locate a single pump atop the fuel filter housing. The unit is engineered for durability with materials and tolerances aimed at long service life in marine environments; confirm compatibility with your engine’s year, model and interchange numbers before purchasing.

Will this pump fit my 1994–1998 Volvo Penta or Mercruiser engine?

If your engine is a carbureted V6 or V8 with a low-pressure fuel pump mounted on the fuel filter housing, this Yeoflagtrade pump is likely compatible. It does not fit GXi or other fuel-injected assemblies that use a different pump design.

• Compatible OE crosses: Sierra 18-7326; OMC/Volvo Penta 3850809, 3854620, 3858261, 3857986.
• Fits many Mercruiser part numbers including 805025A2, 805656A2/A5/A6 and 861155A5/A6.
• Intended for low-pressure carbureted engines in model years 1994–1998.

How does this replacement pump perform compared with the original?

The pump is built to meet the flow and pressure characteristics required for carbureted marine engines, offering a dependable alternative to worn OE units. Yeoflagtrade emphasizes long-life components and manufacturing tolerances to reduce failures and service interruptions.

• Designed for continuous marine use and corrosion resistance.
• Specified for low-pressure fuel delivery typical of carbureted systems.
• Engineered for longevity—rated for extended service hours under normal conditions.

What should I check before installing this fuel pump?

Confirm the engine type (carbureted vs. fuel-injected), the pump mounting location and part-number cross-references to ensure a correct match. Also inspect fuel lines, filter housing fitment and electrical connections to avoid installation issues.

• Verify engine year, make and carburetor-style configuration.
• Compare listed OE cross numbers and Mercruiser references with your old pump.
• Replace brittle hoses, clamps and ensure proper electrical connector fit during installation.

Can I install this pump myself, and are any parts or tools required?

Experienced DIYers can replace this pump using basic hand tools, but observe marine safety practices and relieve fuel pressure before starting. If unsure, have a certified marine mechanic perform the swap to guarantee correct sealing and wiring.

• Typical tools: wrenches, screwdrivers, fuel-line pliers and thread sealant as needed.
• Replace gaskets or O-rings if the original pump used them; check hose clamps for tightness.
• Bleed the fuel system after installation to remove trapped air before starting the engine.

Who this is for: Boat owners, DIY marine technicians and fleet maintainers who operate 1994–1998 carbureted Volvo Penta or Mercruiser V6/V8 engines and need an affordable, direct-fit low-pressure pump replacement. Choose this Yeoflagtrade pump when your existing single-pump, top-of-filter housing setup shows signs of wear, leakage, inconsistent fuel flow or when OE cross numbers match the ones listed. Always double-check year/make/model and part-number interchange information to ensure correct compatibility before purchase.
