I haven't done it yet... but I'd be curious to see exactly what the 
fuel pressure differences are *at the carb* between a pump with no 
return line and a pump with.    Then, if in fact the return line does 
NOT drop fuel pressure a bit, those who say the return line has no 
effect on a YH carb can gloat...
