DEF stuff

Anyone used one of these? The ad came across the top of HEF this morning. I have been using a blue 5 gallon kerosene can for DEF for my 290. The secret I've found to avoid the white gunk is to leave a half gallon to splash around and keep the inside wet. The can I use has a spout that stores inside the can, with a cover that seals it up.

Buy the disposable containers, when tank is full throw away container no matter how much is in it. Much cheaper than any other way of filling def.

We use the risk 3 gallon race jug fill at the fuel depot

we do the same, and we never reuse the containers. They have a bulk tank at the shop for the trucks, and tried to refill jugs for the equipment from it. All it takes is a bit of contamination and

Same here. Our fuel supplier drops off a dozen or so 2.5 gals at a time at the yard when they drop off fuel.

Our philosophy is use the entire 2.5 gals at one time or pour any remaining out - one use jugs. It has worked well for us so far with only 1 DEF injector replaced on our 325FL in 3K hours and (knocks on wood) no issues with the 3 DEF pickups or our D3. With 5 engines requiring DEF it's not hard to find a spot for 2.5 gals.

when the def tank on my Mauldin grader is at 25%, it will take a full jug with non left over

As everyone else has said, always from a sealed container, never reuse a container. Use all the contents and dispose of any leftovers. Crystallized DEF needs serious heat to liquefy. In spite of what you think, it doesn't dissolve in DEF.

If filled from a bulk tank make sure dispenser stays clean, no dried white crust on nozzle.

Yes, DEF is hygroscopic . We had a 55 gallon drum as well, had nothing but issues in winter

It’s amazing how DEF leaks out of every possible connection, hose or weld with the slightest amount of porosity.

I hate doing bulk def, worst thing we've done short of a few oddball sodium and caustic blend lines.

Just like every other fluid, the guys I know that have serious DEF cleanliness issues are also the type to do oil changes with the nasty funnel they found in the back of the pickup or use whatever container for fuel or use old coolant jugs for hydro... lol

If it leaked at a weld then it's obvious the weld was never tested. Testing could be pretty simple and not require an x-ray. Pressure test with air and soapy water, hydrostatic test using water or dye penetrant could also be used. No real excuse for a bad weld.

It’s a union. A little pipe dope on the threads that mate the union might fix that.

I was responding to if a weld leaked not necessarily what was in the pic.

 

[Coaldust]

No worries. I’m picking up what you are laying down. I test everything.

Just the opposite. In DEF, water evaporates leaving a higher ammonia concentration. This is especially true in arid desert conditions. In some parts of the world, it's common practice to drain the tank at days end to avoid quality issues the next day.

It's common practice in many companies to only buy 2007 and older trucks.

Yes, pretty simple. I'm just on my phone but guessing it's PSI on the gauge? When I worked at oilfield tank shops they would test large tanks with as low as 1.5 PSI. It was kind of amazing how much higher it seemed when they released it out a 3/4" or 1" valve. You'd swear there was 125 PSI coming out because there was so much volume going through a small hole.

 

[Coaldust]

I usually use air for testing, sometimes I use water. For safety sake and DOT compliance, 5 psi is the specified test pressure for the 406 work I do. Sometimes, I go to 8-9 psii when I know there is a leak, but I can’t easily locate it.

Of course, for plant work, the FMCSA don’t apply. While creating SOP’s, my engineer explained to me that 5psi air has the same stored energy as 125psi water. So, I’m careful about not getting crazy with the air.
