sag, TC, what’s going price for a pump and heater/sender? Ford f series is 250 for each. No way could 1700 be reasonable for a job like that.
 
Every couple of years, i add a pint of reagent grade deionized water to my def tank to account for evaporation in warm weather.

If you can't get yours revitalized by soaking in dionized water, buy one on ebay. Many who deleted are selling them there. Just get one of those square trade warranties for a year or two.
 
A problem I have at my job is DEF quality- concentration in particular. They like to stockpile the DEF drums in sunlight despite the warnings right on the containers.
Anyway, there is a way to check on your DEF concentration, use a refracometer. One for coolant/electrolyte can be used, or OTC makes one calibrated just for checking DEF specific gravity. Quite valuable information to have. Be one up on the dealer.

1st We manufacture DEF under contract.....Their are no laws to stop anyone form producing it. If you want API cert DEF and want to Pay Blood money that's your choice. Many BIG freight companies produce their own or purchase it form producers, that are NON-API cert.
The correct concentration 67.5 DW and 32.5 Urea bring the freeze point down to 12-14F. This concentration level has very little expansion at it freeze point.

During the summer months I use Deionized water only , when fall arrives I switch back to 60-40% or so.

DEF Evap is a NON- issue I stored Gallons of DEF for 3-5 Years at the Shop and Mark the levels after 5 years 1 container lost 8oz I use this product last summer without NO problems and it checked good after 5 years of Shop storage...

CERT DEF producer want to put fear into users. Keep your DEF tank Full year round will produce better results that running down to Empty and adding. Their is so much myths surrounding DEF, I see why owners have issues with its use... and like X% info today found on the social Networks its founded on tainted info.

Keep in mind I've been dealing with urea for 35 years, and Some of the most wanted products associated with Urea's use in the cleaning business/agent are My solutions.

Just curious if you measure the 67.5% water /32.5% urea by weight % or by volume%??????

If you measure them by volume and change that same quantity to weight percent, then you have 61% water and 39% urea. So your mix could be anywhere between 60/40 and 70/30. This is not a huge swing, but if you are starting with the wrong percentage, and the stock changes relative to temperature/humidity/exposure, someone you are advising could have trouble.

Additionally, if you are using technical grade urea, instead of reagent grade urea, then you can likely get some sodium, chlorine, iron and other minerals in the stock that you are mixing. If you are using urea used for cleaning, i would not chance buying your homemade DEF.

I will continue to buy my ISO certified urea, because i don't know if they report percents by weight percent or volume percent. But they do follow a standard.
I will continue to make my own judgements about how much DI I add. A (former Ram/Cummins) diesel tech on this site once said, "you can't hurt anything by using slightly diluted DEF, but you can clog or damage the system by using too concentrated of def."

Minnesota doesn't have as dry of air as arizona, new mexico, utah, etc. So i doubt that the water will evaporate out of the def as quickly in some states/regions as other states/regions. Also, there will likely be very little evaporation at colder temps as compared to drier temps.

I'm glad you have a business selling abd supplying DEF. But unless you explain exactly which stock you are using, how you store it, and the procedure by which you mix it, i would not try to save money there now that i know how expensive these emissions parts are.

Yea I never looked at the MSDS, and I only linked corcraft to explain the strange source we use. I see no API cert on the barrels.
 
I just looked and deionized water on Amazon is about four times more expensive than DEF. Not sure why you would try and run DW over DEF.
 
Newsa, Its done by volume....and its + - the % ... Its not required to be exact, or needs to be.

You are Also welcome to buy/do whatever you like.....
 
Over the years , We tested just about producers DEF. It very forgiving, another benefit of its use.
Sure if your going to have concentration levels above 50% it will be seen Visually.
