Description Attwood Marine 90° P-Trap Fuel Tank Vent These vents help prevent water from entering the fuel tank, yet allow air to vent freely, during normal sea conditions and washdowns. This eliminates the need for an anti-siphon loop in the vent hose. For 5/8″ I.D. hose. Meets ABYC standard. The arrows in the cross-section photo show the baffled route that water would have to travel in order to reach the fuel vent hose. Compatible with Ethanol blended fuels. Maximum hull thickness 9/16″ Installation hole size 3/4″
