It was so long ago.. I recall looking for the leak back when the fuel line went bad.
When I was installing a new line, I spent some time trying to locate the leak.
I did get it to slow down a lot, but it still had a slow leak somewhere.
The last few years, I left the tank dry and added just enough gas to get the job done.
I'll have to look at it again now, that the fuel line is looking poorly again.
Maybe I'll find a fuel cut-off for the new line.
I'm more of an electronics guy and know very little about ICEs.
Heck, I don't even like changing the oil on our cars.
Sorry I bored you with my retirement stuff..
I'm getting too old to be post here I guess.
