|The fuel vent cover is designed to fit most fuel vents, and will not pressurize the fuel system. The ribbon is nylon with a vinyl coating and silkscreened letters.|
My 58 Cessna has a very small vent tube. This cover worked when others did not.
Just replaced my 15 year old fuel vent cover (the same as ordered here) - it is a great device to prevent material form entering / blocking the fuel vent
Of the (3) covers provided on the ring, the largest oneâ€™s diameter was not large enough to fit over the fuel vent of my 1963 Skylane like a pitot tube cover. Utilized the smaller size and and just stuck inside the tube which doesnâ€™t seem correct but does prevent any foreign objects from entering.
Part number 13-02817 has three size covers included. The I.D. of each are as follows 1) .170" 2) .233" & 3) .366".
