I bet Keystone gets right on it:)
Being you have an older Dodge with 5.9 in sig line.....
You probably know all about what a "bucket test" is. I would do the same type of thing but add on some type of filter.
A sock isn't that great of a filter. Maybe 50 micron if that. Get some type of inline filter that takes it down to 30 or less. Just run fuel/gas over and over thru your filter.
(My latest fuel set up on my 5.9 filters down to 4 micron. Many gas stations only filter down to 30, gas or diesel, per state law. According to in law that talks with those folks often. Unless something has changed of course)
