OK,
All you high tech funnel fanatics out there try this. It really works!
In about 1 gallon of top notch diesel fuel pour in 1/8 cup limestone, 1/5 cup of salt, rock salt is best, some sugar, 2 Black Cat firecrackers, a handfull of 10-10-10 fertilizer and a dash oregano. Swish it all around for 2 minutes and then feed it through Mr. Funnel direclty into your tractor. You can drive with total confidence knowing that Mr. Funnel filtered out all that stuff.
ps, dont' try this with Little Funky Funnel Boy, Jr. Funnel Boy or Uncle Funnel, they are not nearly as good as Mr. Funnel!
