Brass Tee-handle Fuel Filter Drain Valve for all 92-00 C/K trucks. This is a replacement for the brass drain valve locatedon the thermostat housing. This valve connects to a hose that attaches to the bottom of the fuel filter assy for ease of draining sediment/water. It normally has a drain hose attached to it to direct the fluid to the ground. Replace if leaking, damaged or missing.

Don't forget to open your's every few weeks to drain the sediment! Do so with the engine running to expel the fluid under pressure. If it doesn't run out under pressure, your supply pump ssd-045 and OPS switch ssd-011 may be defective. Replace asap.
