Fuel Pump Strainer & Sock Filter in 316L Stainless Steel (AISI 316L (1.4404)) 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 superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L 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 316L 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.
