Hi Mark,

I would suggest that because there is so much room for fuel to slosh around inside the gascolator.  This appears to me to have a self cleaning effect on the filter.  I think it is a better "filter" than an inline filter because the bowl would have to be full of a lot of sludge before fuel flow is arrested.  With a smaller inline filter, I think it would take a very small amount of garbage to clog the inline filter compared to the gascolator.  At least I think this would be true with the one that came with the firewall forward accessories on my Legacy.  It also has a very fine filter, so anything that makes it through should pass through the injector nozzles without trouble.

Thanks,
Kevin
