Leaky Peak Blue DEF box solution!
I put another 2.5 gal Peak Blue DEF in the RAM yesterday using my theory of why they leak. The last two or three boxes I have put in did not leak, drip or have other issues.
When you screw on the spout the little black duckbill vent ends up at the near side of the box(not the center of the box). So to use the box extend the spout and tip the box up with this vent of the high side(like upside down). The vent lets air in from the high side of the spout to replace the DEF exiting without leaking a drop. As the box empties it gets raised up to have the near side flat to the side of the truck.
To say it another way, pour from the high side not the low side!
Try it, you will like it.
