Abstract

A tool for removal of a fuel line from a vehicle fuel module by engagement of and displacement of a locking member, said tool including first and second arms with semi-cylindrical sections at each end that may be used in combination to engage the locking member.

Claims

1. A tool for disconnecting a fuel line having a longitudinal axis from a fitting, said fuel line of the type including a biased, locking ring for retaining the fuel line engaged with the fitting, said fuel line being disengaged from the fitting by longitudinal axis movement from the fitting, said tool comprising, in combination:

a first arm member, said first arm member including an elongate body member with a first end and a second end and having a generally elongate axis from the first and to the second end;

a first semi-cylindrical section at the first end having an axis of said first section generally transverse to the elongate axis, and a second semi-cylindrical section at the second end having an axis of said second section generally transverse to the elongate axis; and

a second arm member including an elongate body member with a first end and a second end and having a generally elongate axis from the second arm member first end to the second arm member second end;

a first semi-cylindrical section at the first end of the second member the same size as the first semi-cylindrical section of the first member and also having a cylinder axis generally transverse to the second arm member elongate axis, and a second semi-cylindrical section at the second end of the second arm member and also having a cylinder axis generally transverse to the second arm member elongate axis,

said first elongate member first cylindrical section and said second elongate member first cylindrical section generally identical in size;

said first elongate member second cylindrical section and said second elongate member second cylindrical section generally identical in size and having a distinct size from the first cylindrical sections,

whereby said first cylindrical sections or said second cylindrical sections may be positioned against a locking ring to effect longitudinal axis movement of the ring and thereby to disengage the ring from the fitting.

2. The tool of claim 1 wherein the axes of the cylindrical members are parallel.

3. The tool of claim 1 wherein the elongate arm axes are straight.

4. The tool of claim 1 wherein the fist and second arms are substantially mirror images of each other.

5. The tool of claim 1 wherein the axes of the first cylindrical sections are coincident when the arms are positioned together for engagement with a locking ring.

6. The tool of claim 1 wherein the axes of the second cylindrical sections are coincident when the arms are positioned for engagement with a locking ring.
