[Tigers] Gas Tanks & Connector Pipes Leakage Testing

[Joe Brown]

If you do have a slight leak it can be hard to find.  Or at least it was
for me.  I would go out for a drive and get horrible gas fumes in the car.
When I got home I would pull the panels out of the trunk looking for a leak
and could never see anything damp.  I finally read somewhere that you can
wrap the joints with tissue paper and that will show you where the leak
is.  It worked for me.  It turned out the hose between the passenger side
tank and the filler cap had tiny little cracks that would leak gas while
cornering if the tank was near full.  I replaced that hose and everything
has been good.

Have Fun,
Joe Brown
