Anyone know of a good quality fuel filter that is small but won’t restrict flow??

If you've got a chandler's near you go see what they've got. Because they are designed for boats they tend to be better quality with thick glass Chambers so you can actually see the fuel flow. Also as they generally located a bit out of the way on boats they are designed to be easily dismantle able in situ for cleaning.
This type of thing.

Thanks warren, I’ll take a look
