Mine were 8 point....I didn't even know about the 4 point till they were posted in this thread. The 8 points came with a socket set I bought years ago, 3 of them to fit the most common pipe plugs.
The less points the better when it comes to not stripping a plug or bolt. Even 12 point sockets/wrenches won't grip as well as a 6 point on a standard 6 sided bolt beacause you go from having contact on all 6 sides and points of the bolt head to just having contact at the tips of the bolt head.
It is the 9/32nd size.
I’ve never taken out the plug before I just thought it was brass because the metal felt soft Looking back there were no shavings on the vice grips so I doubt it’s brass.
I have already checked the usual auto places, Lowe’s, HD, the local 110 year old hardware store, and a few other specialty stores. However I was looking for the 4 point style not 8 point. I did do a brief search just now and I am confident I can acquire the eight point style today however is that going to work as good as the four-point? As I sit here telling myself dont F it up even more lol
being that you have already started to round the corners on the plug I would definitely wait for a 4 point socket, then you can tap the socket on to the plug for a nice snug fit. If you opt for the eight point and it strips the plug out even more oh, that is when the real fun begins
I was just coming back to post the information below taken from the Riffraff Instructions page, but I see this has been done multiple times by now. I guess I should limit my posting to the forum until I have woken up...

(Figure 6) Note: A 5/16” 8-point socket will also fit this plug if available.
will the 9/32 work on both plugs? I thought someone may have mentioned it only works on the passenger side?
Depending on the truck year the DS firewall plug is close to the up pipe and is hard if not impossible to gets a 3/8” socket/ratchet on it. Not only is it close to the up pipe, the vertical distance above the plug is very limited also causing a problem with trying to put a hammer on it.
You were right it is a 5/16" and now that I remember it was kind of big but worked. My engine had all plugs removed when I rebuild it so mine wasn't stubborn as yours.
The job is done DO NOT ATTEMPT WITHOUT THE 8 point or 4 point socket Definite upgrade looking forward to a very easy install on the other truck now that I have the right tool... Of course now the 2000 F250 throttle is responding so well it’s freaking me out about my truck. After putting Upgraded the spring in my truck I definitely noticed an improvement however the Rpms Are not as quick to jump as the 2000 in park Before I did this repair the 2000 was exceptionally slow now If I hit the pedal in neutral it jumps very fast! The fuel filter on the O2 is coming back a little black Every 10 k for over 30 k now. i’m thinking before I do my o rings Which we all know is the main job filled with supplemental add-ons I’m going to change the fuel pump.
Sometimes 1/4 tank is empty other times it’s 100 miles left already changed the pickup foot when I bought the truck....short 50ft tow to conclude the test drive lol anyways best to keep em FULL Plug on the right is rounded and off center 9/32 would no longer fit thankfully the next size up and my brass hammer worked OPERATIONAL
Yes I used a 5/32 on the rounded plug because 9/32 would no longer fit. Than on the other plug that was undisturbed until today I used the 9/32 size. Of course it came out with ease on the breaker bar. I would recommend this set vs buying 1 socket only a matter of time until it makes life easier for again. Another place I’ll use this set is on the differential plugs that way I will feel a little bit more special than using a plain old extension or the ratchet LOL. These impact sockets are made in Taiwan which I like. Soon enough I plan on ordering their 3/4 drive master set. On a side note just got back from test driving the newest addition to the fleet 2011 v6 ranger it’s holding strong!!!
That is a nice set and a much better choice than what I was looking at above. For anyone following, the direct link to Amazon for the @RigCity recommended set is below.
Your differential comment made me remember that the ZF6 has a pipe plug as well as the fill and drain plugs. I have added this set to my wishlist and will break the fittings loose before purchasing any sort of fuel line kit. Thanks for documenting your struggle and success. This thread will serve as a great resource for knowledge for years to come.
the set above has 2 holes in it worst case you could fit a small drift through. There is no room for a ratchet on the passenger side that’s why used the breaker bar. You are welcome I’m glad to get the word out. This would have been a major problem If it was going on my truck first and I was home alone with one vehicle. Thankfully that was not the case I will be leaving a five star review and not some punk 4 star When I receive the email from riffraff for the review
Using the information you linked from clay which I have pasted below...

I found by selecting the second image in the Amazon link I posted above, you can see that the Grey Pneumatic 1211p kit does in fact have the cross drilled holes in the sockets. So, if someone was inclined to purchase a set of these pipe plug sockets, the kit you also purchased appears to be a good one.
I would have thought the drivers side rear plug would have been harder to gain access to, but Clay mentions the passenger side front plug is a tighter fit for a ratchet. Both the information you have shared and the information Clay has listed on his site are very valuable and may possibly save someone the frustration you just went through.
Have you done the Hutch and Harpoon Mods? It sounds like a fuel pressure issue. A new fuel pump may only mask the issues behind the pump. You really should run a pressure gauge on the system and see what you get,
