W-15 & Fuel Stop Inline Fuel Filter
Fuel flow is up to 150 litres per hour together with a water separation efficiency greater than 98% and a pressure drop of only 20 mbar offering minimal restriction to fuel flow. Either transparent or metal bowl options are available and all models are fitted with a washable stainless steel element which means no replacement elements. Installation is before the fuel lift pump ensuring full system protection with two port sizes available, ½'' x 20 UNF/SAE & M14 x 1.5.

The WASP W-15 series has three stages of operation
1. Separation:
The incoming flow of fuel oil changes velocity and direction, reducing the possibility of further reduction of any water droplets present through impact.2. Coalescence:
This takes place on and just below the flow dispersion member allowing the separated water to descend to the bottom of the filter bowl.3. Filtration:
The fuel finally passes through the stainless steel filter element. This removes all particulate above 100 micron still suspended in the fuel after the separation process.

W-15 FS Unique fuel-stop filter
When water level reaches the pre-determined level, the flow of fuel is halted. This offers a safe way to ensure water in fuel contamination doesn’t reach your engine.
The internal precision machined float ensures only fuel passes; it is free to move within the filter and as the water is separated, will float on that water content collecting in the bowl.
The W-15FS range does not offer particulate filtration, hence there not being a micron rating next to the unit's details above, however engine protection from water content is unparalleled in such a compact form.

Installation
- If necessary refit the two port plugs supplied with the filter. If they are not to be repositioned check they are correctly tightened.
- Follow the flow direction according to the arrows on each of the four ports.
- This range of filters should be installed on the suction side of the fuel supply system before the lift pump.
Maintenance
- Check regularly for separated water
- Drain off any separated water or impurities regularly via the thumb screw drain plug or valve
- Remove, clean and re-fit the stainless steel element as necessary
- replace paper element when required, see product range tab
