Anti-Siphon Valve LARGE

• The Anti-Siphon Valve is typically located on top of your fuel tank where your fuel feed hose connects. This is a USCG required part that prevents fuel from leaking into the bilge should a fuel line fail, or gets cut below the tank level.

• Common symptoms of an anti-siphon valve going bad is lower than normal top end or loss of RPM's at the upper range caused by the anti-siphon valve not opening up all the way from internal corrosion. (very common problem on 10+ year old boats)

• Always use Teflon tape on threads when installing.

NOTE: 3/8" hose barb x 3/8" NPT threads - Few ski boats use this valve, most use SBH-0070
