I just replaced my fuel filter with a Beck/Arnley fuel filter. The filter is a good %25 longer and maybe %10 wider in circumference. Talk about a smother idle and acceleration. Has anyone ever T-ed the fuel supply to 2 filters, run dual fuel lines to the pump, and then T-ed it back to a single line to the pump intake? Any notable difference? Seems to me, the pump would output a little higher pressure, but react faster to accelerate.

After swapping out the filter, I had to readjust idle and mixture.
