Sorry, memory doesn't serve well.
I had a gas leak. The location was such that the drips went
directly on, or near, the starter motor. The fix is to find
the leak. Dumb, but not actually, if you get under the car,
and feel around, look around, you'll find the leaking hose,
just by feeling/following the hoses. My leak was just in
front of the place where the fuel line is 'fixed' to a place
on the passenger side of the bottom/inside of the engine
cover 'hole'. (I'm trying to be descriptive). There is a
metal and neoprene connection point for the fuel line as it
comes into, and then on to the engine. From the top, you can
probably find this location and then follow with your
fingers toward the front of the car for a few inches. That's
where my leak was. The fix, new (what? 1/4") hose clamps. It
took three for me, I think. At the points where neoprene
lines connect to rubber lines, and/or rubber connects to a
metal line or the 'fixed' joining point.

My vanagon seems to go along with rubber fuel line, switch
to a neoprene line, then go back to a rubber line (some
places metal lines or connection points).

Near where the fuel line enters the engine compartment. The
clamps rust and get weak, or the hoses deteriorate near the
clamps. I think I put in a section of new fuel line (fuel
line, not just rubber hose).

Again, memory doesn't serve so good.

(I just remembered another gasoline leak. This one on the
drivers side, just behind the driver door, underneath, along
the frame 'joist', the main support frame running longways.
The fix, again, was a 1/4" hose clamp. I took off the old
clamp, cut a new end to the hose (there was enough slack),
and used a new stainless steel clamp. Probably also where a
rubber hose met a metal or neoprene part of the fuel line.
(What's the fuel line doing over there anyway?)
