TESTED - H2Out with Nigel Calder

Nigel Calder, author of the eminently popular and revered "Boatowners Mechanical and Electrical Manual" and "Marine Diesel Engines" books, does NOT do paid endorsements. However, he recommends every boat owner install H2Out "Fuel Guard" Air Vent Dryers in the fuel tank vent line.
Nigel explains the problems inherent with today's diesel fuel supply (even clean fuel bought in the United States) and how the "Fuel Guard" Air Vent Dryer from H2Out solves multiple problems. Which is why the Air Vent Dryer won many awards including the prestigious Pittman Innovation Award in 2012.

Excellent video with a solid concept in preventive maintenance.
Do you have to discard the filter
If you inadvertently overfill your tank at the fuel dock and the filter gets backwashed with fuel?

[@pacificNWboater]

Thank you, Glen. Yes, should you ever overfill your tank and contaminate the desiccant with fuel, the recommendation is to discard and refill with new desiccant.

I was going to ask the same thing

[@TurdsAreOrganic]

I realize the video was posted sometime ago but my question has to do with the fuel inlet volume. With a large fuel capacity of long range trawlers it can take hours to refuel primarily due to the small size of the tank air vents regardless of the inlet size or pump capacity. It would seem to me that the addition of this product in line would further reduce the air volume and further slow down the refueling process. What are your comments or experience with this potential problem?
