What is it with DEF pumps?

They get dropped on the tip where the trip sensor feeds so it doesn't work right anymore and they never replace them. Just look at the end of the nozzle and you will probably see it

 

Sometimes the end is damaged. Sometimes the end has dried chunks of def on it. Out of habit I will tap the tip of the nozzle on the curb to break off any chunks before I put it in my tank. And usually I have to have the nozzle flipped upside down for it to flow good, it must be the way the fill neck is on my tank.

 

I sometimes have the same problem. I usually get DEF whenever my gauge gets below 3/4 tank. That way, if I can't get it, for whatever reason, on that fuel stop, I still have enough for my next fuel stop, or 2. So, when I run across this issue, I'll usually just quit trying to fill it up and instead, get DEF on my next fuel stop. So, I'll end up only getting 1/2 a gallon.
That's how I deal with the problem at least.

 

When filling, hold the nozzle so it's only One inch into the access, do not go all In. The pump pressure and lack of high pressure relief into the DEF holding tank creates a "pressure push back" into the nozzle, therefore Station's DEF Pump reads Full and stops to avoid spillage.

 

When I used to fill up that crap I'd start gently squeezing it so little bit comes out. After few seconds I'd increase pressure and squeeze little harder. Don't squeeze trigger all the way. Try gently squeezing it until it slowly flows out. I also would hold nozzle with one hand while holding hose in the other so that there's slack. Seemed to help.

 

the nozzle has a little pee hole that sucks air to know when to cut off, it gets filled up and trips the sensor. sometimes if you shake it out before you stick it in it will flow free. other times the pee hole is smashed partly closed, then the only thing that works to keep it going is to pump it really slow

 

Shake the pee hole out before u stick it in the hole. This advice can be used for more things than just pumping def

 

You emissions engines guys are just sick. Sick perverts.

 

$4 a gallon for water and ammonia is sick
