Gravity.... such a bee'otch!...

...
If the stock vacsucker petcock gets a leaky diaphragm... fuel will run down the vac line and fill everything below the tank, eventually, settling in the crankcase...
... conversely,.. if yer' float sticks with a Raptor,..(and you leave the petcock in "on" position)
(which I always do)...

...
Fuel will again follow the path of gravity...
The advantage of the Raptor?...
I can turn it off...
What are your options with a leaking vacsucker?... (on, reserve, and prime,... turns into,...on, on, and... on...)...
Ultimately,... I like to be in charge...
...if it leaks?,... my fault... but, if I want it stop?,.. I want that option, too...
I'm a control freak...
