Abstract
Abstract A molded plastic spray guard for a fuel tank vent head of a boat has an inner wall and an outer wall joined by a peripheral wall of U-shaped configuration with a slot extending forwardly from the rear edge of the inner wall to be fittable over a vent line adjacent the hull of a boat between the hull and vent head mounted on the end of the vent line which clamps the spray guard in position. The vent head is consequently protected against contact from spray resultant from operation of the boat to which it is connected but is capable of venting rearwardly through a rearwardly facing opening in the spray guard.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
A spray guard for preventing the entry of spray into the vent head on the end of a fuel vent line of a boat comprising a unitary member having a forward end and a rearward end and including an inner wall having a planar hull engaging surface and a rear edge, an outer wall spaced from the inner wall and transverse wall means extending between and connecting the inner wall to the outer wall to define a chamber of sufficient size to receive and enclose a vent head on the end of a vent line, a rearwardly facing opening in said chamber, a mounting slot having linear side edges extending inwardly from the rear edge of the inner wall and being of sufficient width to permit the vent line to extend therethrough but being of less width than the vent head to permit the vent head to clampingly engage the inner wall between the vent head and the hull of a boat so that the planar hull engaging surface is clamped against the hull to hold the spray guard in position permitting venting through the rearwardly facing opening while precluding contact of spray resultant from operation of the boat with the vent head so as to prevent the entry of such spray into the vent head and vent line.
Claim 2
Dependent Claim
219 words
A spray guard for preventing the entry of spray into the vent head on the end of a fuel vent line of a boat comprising a unitary member having a forward end and a rearward end and including an inner wall having a planar hull engaging surface and a rear edge, an outer wall spaced from the inner wall and transverse wall means extending between and connecting the inner wall to the outer wall to define a chamber of sufficient size to receive and enclose a vent head on the end of a vent line, a rearwardly facing opening in said chamber, a mounting slot having linear side edges extending inwardly from the rear edge of the inner wall and being of sufficient width to permit the vent line to extend therethrough but being of less width than the vent head to permit the vent head to clampingly engage the inner wall between the vent head and the hull of a boat so that the planar hull engaging surface is clamped against the hull to hold the spray guard in position permitting venting through the rearwardly facing opening while precluding contact of spray resultant from operation of the boat with the vent head so as to prevent the entry of such spray into the vent head and vent line.
