passive draining corrected

[shawn74]

TOOK ADVICE FROM CHPTHRIL AND WORKED,had stock hard tank vent connected to inlet of sac and sac vent reconnected to vent in each rear locker. assumed fill pump was passively draining back due to gravity and head pressure.so disconnected fill line from lower tank and looped high over gas fill hose and into top opening of sac with bottom opening of sac tied to inlet of hard tank to allow gravity back feed. tied both sac and hard tank vents together for balance and reconnected to through hull vent.corrected draining and high loop really didnt increase fill time .THANKS CHPTHRIL and fyi has any body tried 3/4" non metallic flexible pvc conduit,prefer it over oem hose ,fits over fittings better,cheaper and readily available

So basically you went from filling from the bottom to filling from the top?

What pumps are you running?
