I've been using an inline filter for about 40 years .
When I removed the float bowls, I always found a few globs of water and fine gritty sediment .
I currently use a pleated paper element filter, Visufilter 8437-03-9909 . .
If you start using an inline filter be aware that it could be too restrictive .
On the first few various filters I started using, I developed a high speed miss after 15 minutes of highway speeds .
