Here s the question in a nutshell: Does it make sense to fill the tank to capacity before the mechanic takes a look at it. 1990 Volvo 740 GL wagon, non-turbo, 160,000 miles. At first, I thought I only smelled gasoline after driving the car home and parking it, and I thought it was when the tank was full. No. Under 1/2 tank the odor exists around the fill cap area. It dissipates fairly quickly. (I never overfill). So, I thought fill hose. But then I took out the junk stored in the back, and can smell the gasoline under the same circumstances. No obvious drips. However, mileage has decreased, but I am driving short distances these days, not to mention that the car has not had a tune-up since I bought it 5 years ago. Tire inflation is solid all around. Driving speed is even. I do not smell the gasoline once the car has been sitting overnight.
I do not work on my car. I researched the problem, and it looked like taking a visual of the hose, etc., by removing the inside panel, was the best way to go, and it didn’t look complicated. My mechanic, however, wants me to fill the tank and immediately bring the car in to look for leaks. If no leaks are visualized, he went to a second option that sounded so unnecessary and time-consuming to me that I can’t recall what it was. He acknowledged that the filler hose could be the problem, but it was only after I asked about the direct visual check that he said that would be the third option.
. Thank you.
