[T2] Good News- inspecting/cleaning a gas tank in place.

[MUTS]

No need to pull the engine- I had a blockage issue on a trip to Ohio 
from NJ and limped home blowing air up into tank line using a Tee I 
installed on the road to unblock the inlet pipe to filter- large pieces 
of a plastic film from a coating a PO had used and peeled off the tank 
walls and laid over the outlet pipe.  Once home I did this:  Drain tank. 
Cut the wall over the tank level gauge with a dremyl disk and take out 
the gauge.  Stick a shop vac line in there to BLOW out the tank with air 
and it will evaporate the gas.  Same trick I use to flush out a septic 
tank to climb in there (after pumpout) and check/clean the root- blocked 
sewer inlet.  Drop a led light into the tank and inspect at night using 
a a mirror glued to a wire. I found pieces of this failed coating and 
used the vac with a flex propane line taped to vac end. The vac used 
extensions so it was at least 20 feet from me.  Flex line wails like a 
banshee with air flow, use ear protection!  Sucked up all the pieces, 
and have had no problems since.  I kept the the Tee so I could blow up 
air in there if needed.
