The 'Pencil' filter and standard bowl filter do NOT remove debris from the gas tank - the 'Dog Leg' does. Slowly and over a bit of time (six months, or so), with constant 'cleaning out' of the Dog leg, IT DOES clean out a great deal of the rust, tennis balls, and other junk in the tank. Certainly not as good as (gasp !) removing the tank - but a workable alternative that will go a long way to reducing the fouling of the two filters. - After the six months of driving and constantly cleaning out the Dog Leg, when the gas tank finally becomes 'miserly' in depositing debris in the Dog Leg, then it is time to install the 'Pensil' filter.

Junk will still continue to accumulate, but at significantly greater intervals, with MUCH more driving time before the issue once again becomes active. So DON'T throw your Dog Leg away ! You will probably need to use it again every couple of years. Remember, the gas tank interior will continue to flake rust particles, as part of the problem of using a 85 year old 'tin can'. It still beats yanking the tank out, which is required to do the job 'properly'.
