  One thing that people should also note is that when you use a heavy fuel
system cleaner be ready to change your filter within a few days.  The
cleaner also does a good job of loosening all that sediment that is in the
tank after all those years.  I found that when I used a heavy cleaner on my
van and then went up a very bumpy mountain road I changed filters every
three days for 5 filters after that trip. Was getting ready to drop that
tank and do a flush.  A tank that I just dropped (a 70s ford) and flushed to
see if it was a keeper had an almost unbelievable amount of sludge rinse out
of it. That tank was pulled from a running vehicle not a salvage yard dump.
