TM-10-1513 May 15, 1942 ..... page 125 under BODY.

"Brass plugs have been placed in the left and
right front corners to drain the floor".



TM-10-1206 Dec. 1, 1941

page 76 grp No. 1800 Body & Attaching parts
A-2933 ....... Clinch nut- special (for 1/4" pipe drain plug in front floor) .......................No. reqd 2
52984 ........ Plug 1/4" - pipe thread - Slotted (for front floor pan drain hole cover)..........No. reqd 2

page 84 grp No. 2304 Pipe Plug
5138 ........ Pipe plug 1/4" Std............. No. reqd. 3
52984 ...... Pipe plug 1/4" (slotted) ....... No. reqd. 1 I assume this is a misprint as 2 are required.


TM-10-1186 July 1, 1943

page 137 grp No. 1800 Body & Attaching parts
A-2933 ....... Clinch nut- special (for 1/4" pipe drain plug in front floor) ......................MB ...No. reqd 2

page 49 ... picture of fuel filter... Willys part No. 5138 .... Ford part No. 353055-S ...Pipe Plug - 1/4"

SO................
5138 is the Willys part number for the square head standard 1/4" pipe plug used on the fuel filter(2) and the fuel tank drain (1) for a total of 3

52984 is the early 41 - 42 part number for the 1/4' slotted floor drain plug ( most likely the brass ones )

5120 is the later 42? early 43? onwards part number for the 1/4" slotted floor drain plug ( most likely changed to steel )

And that same slotted plug also is used on G-503 fuel tank drains.

Everything I've read says that the square head plugs were used in the tank, but you are saying slotted? I'm glad I still have my square head drain plugs so I can quit paying attention to that half of the conversation. I guess I will be looking for some slotted plugs for the floor though.

A-5120 Plug is in the TM10 and SNL's, some say just Pipe Plug, others describe it as "slotted", it's in the manuals, you have to hunt for them, group o300 and 1800 will list them. It also is used a bung in the fuel tank drain. The they have been popular with the MVCC members since the 70's. The ones I have are slotted brass.

My jeep had a square head plug.

The pal nuts were still on the brackets and the tank had never been removed. You can see the pipe plug was primed at the same time as the tank and the tank installed before final painting.

As I stated previously in this thread I think the brass slotted plug turned into the square head sometime in 1942.

Hey Ben....can you confirm they are about .42 inches long and are they FLAT or arched where the slot is? I'm checking with a distributor to source them here in quantity.

Hi Chuck,

The iron pipe slotted plugs and Ben's brass slotted plugs should look great in a GPW.

I have quite a few of the steel slotted plugs in vintage old boxes ( looks to be close to .42" tall and have a slight dome on top ) but I will no longer sell them in steel or brass ( if I had brass ) to unsuspecting GPW owners unless that is what they want.

Tom...this style of plug....iron pipe threads, slotted or sq. headed, brass or steel were around for along time before the designers of the jeep found them on the shelf at the 1930's version of ACE Hardware. They have many uses besides jeep floor drain plugs so I am not surprised they can be found in old-time boxes.....the oil galleys use a steel sq. head plug, the draglink uses a slotted head style plug, so they were in use as automobile parts prior to the jeep.

..however, before you put them on the back shelf, I think we need to investigate a bit further to discover if in fact that there was not a move away from brass to steel or if both were purchased for installation at some point in time.....and if there was a move to use the sq. head ones in steel only....I am not sure about this myself, but I think if the slotted brass ones are available to use in your restoration of an early WWII jeep that this is what it would have had from the factory. As far as mid-war or late war production goes....I am not so sure....

I have come to the conclusion that the manuals, be it a Ford or Willys, do not maintain continuity in the description of items and may say 1/4" BRASS SLOTTED PLUG in one and 1/4" SLOTTED PLUG in another and possibly even 1/4" PLUG in another. That may mean something changed or it may mean the person who worked on the manual changed...and changed the wording.

PS...I meant that I have sourced some 1/4" I.P. Slotted Brass Plugs that are .42" long....not that I have found some made from "iron pipe", these are brass also....I'm interested to see if Ben's are domed and if the ones I will get will be domed....
