Anyone have a source for that yellow plug that lets you drain water from the separator at the fuel filters? Mine is leaking and dealer says they’d have to replace the whole assembly at $$$. It’s just that o-ring.
I thought you should use the yellow drain to make sure the water is removed. (I know we have a sensor)This has come up before. AFAIK, the only way to get the plug is to buy the entire housing.
If it's broken/missing/leaking, I would consider very gently tapping it for a pipe plug. Once sealed, I would never touch it again.
I don't use the yellow plug, because I'm afraid I'll break it.
If you have a Mac's in your area give them a try. We have one in Fargo where you can find any o ring. There's even this short Irish guy who can find you anything in the store. As someone else mentioned I don't like the position of that plug. Looks like an errant corn stalk could pop it right off easily. Guys on here have over a grand into a full set of the superskidz and yet a plastic plug on a plastic housing that holds their fuel is level with the frame rail.Thanks all. I’ll try an o-ring search. If I find a good match I’ll post it.
The correct Oring is a #41 9/16" O.D. x 7/16" I.D.It would be much cheaper to just buy the O-ring. Even if you have to buy numerous o-ring kits to find the right one. Somebody has to make one that fits. Just make sure they are diesel fuel compatible.

I have not had to change my fuel filters yet, but just by their flimsy design of the water/fuel drain plug, I have thought about having one made at a machine shop, out of aluminum. It just looks like a fail point for off-roaders.
Exactly! The aluminum factory remote oil filter mount on my S10 ZR2 rotted away and left the oil filter dangling by the lines.Corrosion resistance. It’s a harsh environment under the truck, especially in places with winter. The salt would eat the bare aluminum pretty quickly.
I’m aware of that thread. None of the items suggested are proper or good solutions. Nylon and diesel is a no-no. It also absorbs water and swells. Also, people are using the wrong o-ring material. The factory material is flourosilicone and they are blue. Viton is probably OK if you replace it when you replace the filters, other wise it could fail. Butyl is a no-no with diesel, plus it is too soft and easily damaged. Also, the housing is aluminum. Brass reacts with aluminum. Steel and even stainless steel will also react and you will find them frozen in place or the thread will come out with the plug. I looked into using plastic, Torlon PIA is the proper material as it is OK to use with diesel and it does not absorb water. But it costs $61 a foot while aluminum is under $6 a foot. Those are McMaster-Carr prices, so there is more savings to be had with bulk purchases from other vendors. Even with the added expense of anodizing its still way less expensive.
