I'm running a high quality Racor 500 copy with a 30 micron water block element as a primary filter, and a Cat 1R-0750 2 micron filter as the secondary filter.

Lots of issues due to contaminated fuel before I installed this upgraded filtration, no issues since.

It's also completely overkill for just about everyone. Almost all of these engines run the factory filtration, and the injection system outlives the engine and car.
