OIL STRAINER

An oil strainer for a full tank typically refers to a filter or screen in a fuel or oil tank that prevents contaminants from entering the system during operation or refilling. These are common in automotive, marine, or industrial equipment like generators or heavy machinery.

• Purpose: Removes debris (e.g., dirt, metal particles) from oil or fuel in the tank before it reaches the engine or system, protecting components like pumps or injectors.
• Types:
  • Fuel Tank Strainer: Often a mesh screen at the tank's outlet or filler neck (e.g., nylon or metal mesh). Examples include strainers for diesel fuel tanks or marine outboard motors.
  • Oil Tank Strainer: Found in hydraulic systems or engine oil reservoirs, typically a coarse mesh (40-100 microns) to catch larger particles.
• Materials: Stainless steel, nylon, or brass for durability and corrosion resistance.
• Maintenance: Strainers can clog when the tank is full due to increased flow or stirred-up sediment. Regular cleaning or replacement is key, especially if the tank has been sitting or contains old fuel/oil.
• Issues: A clogged strainer can cause low oil/fuel pressure, engine stalling, or pump cavitation. Check if the strainer is removable for cleaning or requires replacement.

Specific Examples 

• For vehicles like the Yamaha outboard or Kubota tractors, fuel tank strainers are often part of the fuel pickup assembly. A replacement might cost $10-$50.
• Industrial oil tanks use basket strainers or inline Y-strainers, often rated for high flow (e.g., 10-100 GPM).
