Ok - here's one for the experts.
After returning from a weeks vacation I do an oil change on the 914. When finished I start the car up to warm up and get the oil going. I run the car for several minutes then shut it off. While checking for any surprising oil leaks I find a wet spot under the car (no it's not THAT!) below where the fuel pump and filter are ( 1972 stock location). I start the car again and drip, drip, drip, you can watch it leak. Shut the car down. I jack up the car to get a better look at the fuel pump and filter area. It's all dry by this time, so I start the car again - NO LEAK. Whiskey Tango Foxtrot? I've let the car sit over night, started next day, still no leak.
My theory is the car hadn't been used in almost two weeks. It's been a daily driver mostly. perhaps a hose dried enough that it leaked, and once I ran fuel through it the line swelled and now doesn't leak. Obviously I'm going to replace the hoses around the filter and fuel pump. And one winter project will be to move the FP up front.
Has anyone else experienced this odd phenomenon? Or is it just me?
