## Questions & Answers

**Q: I have a 2019 mercedes sprinter. is this the fuel line connector needed to install an epar d-2 air furance?**
A: Well , i used this connector to repair a damaged and broken gasoline fuel line. If your unit used liquid fuels such as gasoline   it should be ok , otherwise i am not quite sure...

**Q: Hi will this work on a 2006 sprinter t1n? thanks!**
A: I used it on a 2007, so not positive.  I would ask a parts/ shop guy at the dealership if there is anything different between the years.

**Q: I have a 2019 mercedes sprinter passenger van will this work with that given it already has a supplemental heater for the unit?**
A: On my 2017 sprinter the single spare fuel line coming from the tank is what I used with this adapter. 
Not sure if you need a splitter if more than one accessory is attached

**Q: what size line fits this adaptor?**
A: These snap onto a 5/16 port. And a 6mm nylon line fits on the barb.

### ⭐⭐⭐⭐⭐ Worked on my Sprinter's Aux Fuel Tap
*by E***R on December 16, 2021*

I used this to connect my 2020 Sprinter's aux fuel tap to an Eberspacher D5E heater. Clicked right in, worked perfectly. I don't expect to need the second one, would have been nice to just order one, but that's ok. Don't forget to keep the old cap for the aux fitting just in case you have to do maintenance!

### ⭐⭐⭐⭐⭐ Sprinter aux fuel tap
