This 31-micron synthetic sock filter is designed for use on a high-pressure fuel pump mounted inside a fuel cell. It features an integral plastic skeleton to prevent it from sucking closed under high fuel draw.
Measures 2 1/8" x 3 7/8" (55mm x 98mm) with a 7/8" (22mm) opening. This is the same filter supplied with our High-Pressure In-Tank Fuel Pump (Part No. FS FPHP).
We also offer a Sock Filter Adapter (Part No. FS 1HDW52, sold separately) to mount this filter to the Bosch "044" High Output Fuel Pump (Part No. FS FP044, sold separately) to keep your Bosch pump running in top condition.
