Davco 382 / fuel filter not filing up

I think you’re making a mountain out of a molehill. If you did install it wrong, you would have issues with running engine by now.

 

When it's full it's time to replace the filter, when its low it's still a clean filter. Davco filter setup is the best out there for this reason imo.

 

What @StrokerTSi said

 

When the fuel reaches the top, time to change it.

And if you're leaning the truck to either side really good with less than say a 1/4 tank, itll transfer to the low side and you'll suck air.

 

Mine is the same way since I changed it about 10 days ago. Mine has never ran that low for very long. Truck is running fine, maybe just getting some clean fuel. The level only goes up as the filter gets dirty/clogged.

What brand filter? I put a Baldwin on this time, usually use Luberfiner or Donalson.

 

This my experience with the detroit filter as well vs using a Baldwin. Baldwin may filter more microns then detroit, I prefer the detroit filters, they're cheaper for from the dealer and last longer.

 

Ive had this same question with the same engine. Mine does this occasionally when I change the filter and put fuel back in(about an inch up on the glass) It goes down and doesn't come back up for a bit sometimes. It still runs fine and no bubbles that I can see..... Give it some time the fuel level will raise up.
