Diesel Fuel additives and filler neck frustration

I checked their website and distributor map... sadly, none in New York and few in PA.

Maybe someday...

 

Hi: I use the one supplied with the truck,a white one that is under the passenger seat.The mouth is not wide but is long.

 

$3 funnel, ziplock and a toolbag https://www.harborfreight.com/11-in-tool-bag-with-3-pockets-61168.html in the bed. I live on dirt roads and have 3 bags (recovery, drophitch and funnel and misc) and the contents are clean.

I also have one in the garage, I usually do my adds there. Took a old pain can with kitty litter in it, punched a hole in the lid big enough for the funnels to fit in. The funnels drip into it and no mess on the work bench.

 

In my new 2020 quad 2500 TDC there are two infloor compartments, left and right, under the floor mats in the back seat area. I keep the small bottles of Hot Shot EDT and LX4 in a zip lock bag, along with the OEM funnel, which was under the passenger seat, with a rag thrown in. No muss, no fuss, no smell.
