[Spridgets] Gas leaks

[Kitterer Bob]

OK Folks I am out of ideas.

At freeway speeds I can smell gas but when I stop it is not apparent  
where the gas is coming from.  It seems like it has to be the float  
bowl overflows since all the lines are good and if they are leaking  
speed should not make any difference.   For some years I have been  
fighting grit from the gas tank - - powder coater blasted it with out  
taping the openings after the tank had been cleaned.  Ran lots of  
paint thinner through the tank before reinstalling, added two in line  
fuel filters and grit still got through. After five sets of filters  
and float bowl jets and needles I thought the problem had been licked  
- - no more over flow at idle.  The pump pressure is also correct,  
check last week.  But still smell gas at freeway speeds.

Thoughts???

Thanks
