Def refills

I am using 2 tanks of 2.7 gallon capacity. When I refill at Pilot/Flying J, I do not have any problems with the flow at the pump. However, when I go to Loves(which I like best), the pumps do not operate properly. It takes forever to fill the tanks. How can I fill the tanks at a fast rate??? I am sure this issue has been discussed before bui I could not find the info.

Loves uses a flow restrictor on their DEF nozzles. You need a magnetic collar placed around the fill neck of your container to override the restrictor. You can ask at the cashier where you pay for your fuel to borrow one before using the DEF pump.

Jimbo41 and all RV owners with Clean Diesels:

Many truck stops now use the Magnetic Interlock DEF Nozzles. This "feature" makes it less likely that users will put DEF in the diesel tanks which is a very expensive mistake. Expect most, if not all, bulk DEF pumps to have these nozzles before long.

These nozzles are designed to NOT flow (or flow very slowly) unless a magnetic field is applied in a very specific location on the Nozzle spout. How do I know this??? In response to requests from several IRV2 members that have purchased our DEFJUGs, we bought an OEM magnetic interlock nozzle and tested it. I took it apart and figured out how it worked. The nozzles are fairly complicated, and the magnetic interlock is added to the automatic shutoff feature that has been in use on nozzles for a long time.

We bought a bunch of different kinds of ring magnets until we found one that makes the nozzle flow at full rate. We designed, built, and tested a no-frills device that works great and stores easily in your vehicle. It passed our drop testing and other tests that we run on all our products.

We came up with a cool name for it - The DEF Magnevator.

I've made over 70 of them MYSELF. I test each one on our magnetic interlock nozzle to make sure it works. We've got over 500 of the ring magnets here in our shop and have no problem getting more of them.

We now sell this device that makes filling our 2.7 gallon DEFJUGs, other jugs, and your RV's DEF tank a breeze when faced with a magnetic interlock nozzle. They are a lot less expensive than the OPW-MFPD product (which also works great - we have one), and are guaranteed to work. You can purchase them at our website

DEF Magnevator - FiveStarDEF.com

or on eBay

Def Magnevator by Five Star Def Activates Magnetic Def Nozzles at Truck Stops | eBay

for $13.50 which includes shipping in the US. We've sold over 25 of them with great results.

Look for all of our products on Amazon later this year!!!

As always, don't hesitate to ask us questions about DEF!!!
