Fuel Pump Strainer & Sock Filter in 304 Stainless Steel (AISI 304 (1.4301)) is used for pre-filtering fuel at the inlet of in-tank electric fuel pumps so rust, sediment and debris do not wear the pump. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Fuel Pump Strainer & Sock Filter Is Used
- Fuel pump OEMs: in-tank inlet socks on pump modules.
- Aftermarket replacement: strainers sold with or without pumps.
- Motorcycles & small engines: compact strainers.
- Marine: outboard and inboard fuel pumps.
Ordering Fuel Pump Strainer & Sock Filter in 304 Stainless Steel
- Inlet fit: Push-on diameter and orientation must match the pump.
- Micron rating: 40–70 µm protects the pump without restricting flow.
- Media: Stainless dutch-weave resists ethanol fuels and does not swell like nylon.
Mistakes to Avoid with Fuel Pump Strainer & Sock Filter
- A kinked sock that starves the pump at low fuel levels.
- Fitting a finer strainer than specified, which causes vapor lock in hot weather.
