Message-ID: <233580101.134625.1756908187700@connect.xfinity.com> Tigers, I went out into the garage the other day. The smell of gasoline was overpowering! I emptied the three cars and let the garage clear. I put the Tiger back in the garage first and closed the garage doors. Twenty minutes later the smell of gas was evident. There are no leaks, puddles, etc. I checked everything. I started the car and let it warm up - nothing seems to be wrong! Ideas would be appreciated.

I had a smelly garage recently but I think it was mostly from the several days of 90 degree heat. I also had a mechanical connection that was very slowly weeping some fuel; I only saw a fuel stain Unfortunately, Tigers have many connection points and every one of them needs to be carefully examined. Mechanical connections for any signs of weeping fuel stain Rubber connections for cracked rubber ? rubber hoses sometimes need to be removed to see if they are internally cracked Steel tubing connections need to be checked for weeping fuel Steel tubing should have a bubble flare at any rubber hose connection Rubber hose clamps could be loose or not working correctly as in not enough clamping force Steel tubing should be captured at various points along the body ? vibrations can cause a stress fracture in the tube, you should see a fuel stain at the fracture point Hope this helps and good luck Ron Fraser From: Tigers On Behalf Of Theo Smit Sent: Wednesday, September 03, 2025 2:22 PM To: Dr. T.
