Does anyone know the size of the Riddler covers allen head fill plug.. I called Rokmen and they could not tell me??? WTF the people who pitch these dont know what size the fing plug is?? Some help they were, they told me to put a tape on it and measure it. WOW is all I have to say. So for anyone here that has the covers (d44) and knows the size of the allen head fill plug please let me know. Thanks!! JOE>

 

Did a quick Google search and found a post on another forum where they said they replaced the Riddler fill plug with one from a stock D30. Should be easy to look up the D30 plug size.

It's the internet, so it must be true!

 

I put the stock ones back in mine so I would not have to use an allen wrench
I will look @ mine when I get home if you don't have an answer by then

 

Its a 3/8 allen.

The fill plug is 1/2" pipe thread with a 3/8" allen socket. I changed mine to 1/2" pipe plugs with hex head so I could use a standard wrench on them.

Since the devil's in the details, is the 1/2" NC or NF? (or is "pipe" thread always coarse?)
