High Efficiency Diesel Fuel Filter Water Separator 1000FH 1000FG

OE-grade 1000FG 1000FH fuel water separators are heavy-duty filtration parts engineered for diesel engines of trucks, construction/agricultural machinery, marine vessels and generator sets, ideal for direct OEM replacement with no modification needed.

1000FG Fuel Water Separator – Common Manifold Configurations

The 1000FG fuel water separator is available in 1-bank, 2-bank, 3-bank and 4-bank manifold versions, with 1-bank, 2-bank and 3-bank being the mainstream options for most industrial applications, all perfectly matching the original 1000FG filtration performance and installation specs

Key attributes

Crafted with industrial-grade materials, the 1000FG features a thickened high-strength aluminum alloy head for extreme pressure/corrosion resistance, while the 1000FH boasts a compact, detachable filter bowl for easy maintenance. Both models are fitted with a 5-micron hydrophobic filter element, delivering 99.9% water separation efficiency and 99.5% particulate filtration efficiency—effectively removing free/emulsified water, rust, sand, sludge and asphalt from diesel fuel via centrifugal precipitation and hydrophobic adsorption dual technology.
