I'm not sure why.

An adequate summary is Chapter Seven:Lessons Learned on page 43.

I'm told that, when standing still, the fuel just seeps out of the thing. Something about the way the panels fit to allow for heat expansion?

I became a bit upset the first time I refueled the thing,and the crew chief was pretty amused when I went to a lot of trouble to get his attention and tell him that his bird was leaking.'one of those f n g moments.
He said that under flight conditions the things tightened up and sealed up 'n not to sweat it.
The guys in the spacesuits never seemed to be bothered by it,so I learned to relax around 'em.

We used it to "wipe-down" our planes after every flight so the engine mechanics could *see* IF and from WHERE the oil leaks were.

However, it DID leave a nice WHITE exhaust pipe in my '65 MG Midget and NEVER had any engine knock or ping (ha,ha).
