I meant to say 1/8-27 NPT not 1/4.

I would like to install a drain plug on my polypropylene gas tank and am wondering where I can buy a 1/8-27NPT plastic plug. Anyone know of a source? I don't want to buy a bag of them - just one or two. Thanks.

I think 1/8th inch is 27 TPI...1/4 is 18? as I recall.

Check your local HW/Home depot?

Home Depot doesn't sell small plastic ones with 1/8-27 NPT threads. I need either nylon or polypropylene.

Go to a place that does underground sprinkler installations.

Does it really have to be plastic?
The option that I would consider is a stainless steel Allen plug (less sticking out to get knocked off )
Such as this from Grainger---

How about aluminum? There is always ebay. Not too many items not on ebay. Summit Racing also has them.

How are you going to get the threads in the tank body?

Gosh, I went to the Fastenal website earlier and couldn't find them.

I will drill and tap a 1/8-27NPT hole in the bottom of the tank. Already tried it on a practice piece of polyethylene plastic and it worked fine with no leaks. The trick is not to tap too deeply with the tap, otherwise you loose the taper.

Is this a Tanks tank?

Let us know how it works out.

I bought a Tanks Inc universal tank for my project and never realized that it used an in-tank fuel pump. The pickup came out the top of the tank. Had to have a bung soldiered to the bottom. They should put drain plugs in their tanks.

OK, I will. The tank is a polyethylene tank from TANKS.
