On my project Boxster S the oil filler tube that goes from the trunk to the engine had a hole in it. A loose piece of insulation foam rubbing on it wore through the tube, not very solid.
A new one is well over $100 delivered here in Canada... so I said to myself, "there has to be a cheaper way".
A flexible radiator hose looked like the way to go, a 1.5" ID tube would do the job. My idea from the start was to connect the radiator hose to the engine end of the old tube. Unfortunately when the radiator hose arrived it was too stiff to bend easily. So I fabricated a bracket to give it the necessary shape.
A piece of 1.5" plastic tubing serves as an adaptor.
Here is my bracket.
Installed in the bracket.
And the finished product as it will be installed.
A radiator clamp will hold it on the trunk end and a zip tie to hold it in the bracket. Total cost: $30 in materials and about $75 in labour... if I paid myself minimum wage.
