[TR] TR2/3 gas tank question

[Angelo Graham]

  Hello List:
Re-installing my gas tank after it has been sitting indoors for some 
time. I originally had the tank cleaned at a rad shop and I sprayed the 
inside liberally with engine storage spray before storing it. The tank 
looked great, with no crud or rust on the inside. The tank now has a 
light coat of powdery rust on some of the inside panels.
I sloshed a mixture of gasoline/varsol around the tank and it came out 
rust brown. Can't see beyond the baffles in the tank, but it does look 
cleaner where the solvent/gasoline washed it.
Should I expect problems from this light coating of rust? Will it 
overwhelm the in-line gas line filter in short order? The rad shop 
fellow said it shouldn't be a problem.
Any advice on this?
Thanks in advance.
