Has anyone who has run the 2micron fuel filter setup encountered a mysterious leak from the filter under high loads (ie heavy towing). I haven't been able to locate the source of the leak yet. It is not a major leak but enough to cause a fuel drips off of the bottom of the filter. I have tightened the lines and hoses, I have made sure the filter is tight. It is also on it's second filter so it is not just a bum filter seal. There is fuel pooled in the recess on the edge of the filter between the filter case and seal. At first I thought it was bum filter gasket, when I last changed the filter I made sure the seal was ok and sealing surfaces were clean. It didn't leak for about 500km until I towed some heavy hills and now it is showing signs of leaking again...

Any thoughts?

 

I had to pull my lines going into the filter housing and also the line going from the housing to CP3. Re sealed with an extra wrap or 2 of Diesel rated thread tape and never saw a single drip again. You might call Glacier they are great to work with and if defective they will send a replacement. Hope that helps!
Ps, I did notice on my first filter change that the rubber seal on the center post of the filter mount comes off when I take the filter off. I have to hold it there while I put on a new filter but seems to seal fine

 

x2, I also had to remove the 1/2 & 1/4 fittings into and out of the filter housing and reseal. Very easy fix and no more leak. It was only a slight leak to the tune of a couple drops a minute.

 

I had a similar issue when I first installed my 2u filter kit from Glacier. I did use thread tape the first time but it leaked just enough to wet my finger when I ran it under the fitting. All that was needed for a fix was a little more torque. I've not had a problem since.
