Well, there are 26 to 32 or so clamps on a Vanagon fuel system (depending on
if you count the fuel injector hose), though the factory originals are a
crimped clamp type and not adjustable. Someone may have replaced the lines
at some point so you better check them all. What would concern me is the
clamp on the hard plastic supply line to the fire wall adapter. This line
is notorious for popping off and causing fires. It's cheap insurance for
you to order a kit and be sure it's done right with high quality line and
clamps. Eliminate the firewall adapter while you are at it, it's failure
prone too. Check the vendors and pick your favorite.
And, the switch sends the wrong signal to the ECU when stuck closed and
engine runs too lean and bucks like crazy.
Reseal the fuel tank too while you're at it! This will give you a full
weekend of fun!

I have not driven my vanagon for about two months. I charged the battery
and the engine started normally. When I walked to the rear of the vehicle,
I smelled gas so I immediately turned off the engine and investigated. The
gas was leaking from the drivers side injector manifold. There were _no_
leaks there two months ago. The hoses showed no cracks and were still soft
and pliable. For grins, I tightened all of the hose clamps. All of the
hose clamps were loose. I could have tightened the screws on the clamps one
turn by hand. After snugging all of the clamps, the leak stopped.
I do not remember reading this type of experience in the vanagon list
before. Is this a sign that _all_ of the fuel hoses need replacing?
Another question. Why does the engine RPM change rapidly when the idle
switch sticks and the throttle is opened? The symptom of RPM changing had
me baffled. Every time I experienced this symptom, I pulled over, opened up
the engine hatch, and manually operated the throttle, the switch did _not_
stick. I even opened the engine hatch at home, started a cold engine, and
manually operated the throttle, the switch did not stick. After sitting for
two months, the switch was finally stuck when I manually operated the
throttle.
