The carb bowl drain plug on our Ford 600 started dripping gas. I have the shop manual but there is no part number listed for this and Steiner and Tractor supply only sell the part in a $60 kit. Does anyone know the specs on this part? If it is a standard size I can get it from a hardware supplier, but I can"t really get the specs from the plug that"s in there because it is just a cutoff machine screw from the looks of it and doesn"t have the conical seat at the end where it seals with the carb bowl casting. Thanks.
 

The drain plug is basically just a 1/8" pipe plug, available at most any hardware store, but from the way you describe it, maybe you're talking about something else?
 
Thank's Rusty. This is a lot bigger than 1/8 inch. I found a picture of it online in a listing for a repair kit and it's a brass plug with a conical seat, about 3/8 inch diameter at the threads. The one that's in there now is just a plain plug and it's steel and it leaks. I'm going to check the repair kit manufacturer site, if I can find it and see if I can order just the plug.
 
A good hardware store will have that plug in brass. I'm not talking the hardware department at WalMart though.
 
Thanks. After the holiday I will check the local S&H as they have a lot of hardware and fittings. I'll dig up the specs on it somewhere.

A 1/8 pipe thread is about 3/8 diam. 1/2 inch is about 3/4, 3/4 is about one inch. Maybe somebody who is a plumber knows why.
 
Never had a ford carb apart, had an A/C and a half dozen Farmall carbs apart and they all have an 1/8 inch pipe plug for the bowl drain. If you have a decent tap and dye set it should have a 1/8 " pipe tap in it witch is about 3/8" in diameter to compare to what's in your carb.
 
Thanks for the information. I don't know all the plumbing parts, but if this is a standard item I should be able to find it at the local hardware. Seems like a common item to lose considering how many times I had the one out of the old 8N.
 
I'll have to ask the neighbor, who's a plumber, why they are called what they are next time I talk to him. If it's a standard part I can see why the tractor part shops don't sell it.
 
re:pipe thread. pipes are measured on inside dia.for obvious reasons. so the outside thread has to be larger to allow for the pipe wall.
consequntially, a 1/2" pipe, schedule 40,will have an outside diameter of approx.3/4"
And so on for other sizes.
