9/32" Square Female Pipe Plug Socket

Part Number:

9/32" Square Female Pipe Plug Socket for Ford 7.3L 99-03

These can aid in the removal of the fuel test port plugs on each head, which is required to install the FRx. The socket is a tight fit on the passenger side plug so we suggest not using a ratchet, but use only the socket and something like an Allen wrench through the cross drilled holes in the body to unscrew the head plug.

  1. Couldn't use it 3 Star Review

    Posted by on Sep 19th 2017

    The item itself is great, it looks just as well made as any other socket. My problem was that it's a 3/8 drive and not 1/4 drive. In a 3/8 drive setup I couldn't get it on the passenger side plug and was only able to use it to break the driver side plug loose, only reason for 3 stars.

  2. You need this 5 Star Review

    Posted by on Mar 4th 2017

    Tried to remove the front passenger square plug on the fuel rail for the FRx install on my 7.3. After failing with wrenches and vise grips due to the tight space I finally ordered this. I missed seeing it when ordering the FRx. Save the grief and buy this when getting the FRx. Money well spent.

  3. Great product 5 Star Review

    Fit was perfect, well thought out design

  4. Solid product 4 Star Review

    Solid product but my 1/4" drive universal socket actually fitnin the confined spaces much easier.

    As the headline says, drivers side great! But with the HPOP res. in the way it's difficult to use on passenger side head. Otherwise I would have given it 5 stars.

  6. Solid impact grade socket 5 Star Review

    Posted by on Nov 13th 2016

    It made removing the plugs for installing the FRX lines into the heads easier. It works great, if you have a low profile ratchet or a universal joint, otherwise it wouldn't work for the passenger side.

  7. Another Great RiffRaff Product! 5 Star Review

    Posted by on Oct 20th 2016

    I purchased this with the FRx, and I know it will be a "one time only use", BUT I have seen my share of square-head bolts round-off. Makes the job easier, and gives a good piece of mind. The bolt in the front (passenger side) was too close to the HPOP reservoir to connect a ratchet, so I just placed a hardened steel pin-punch in the holes on the side of the socket and used the punch as a lever...worked like a charm!

  8. A must buy 5 Star Review

    Posted by on Sep 21st 2016

    For anyone that owns and works on their 7.3 PSD, this tool is a must have in you're tool box. Should be a part of any kit that involves changing out fuel pressure feed lines.

  9. Do yourself a favor 5 Star Review

    Posted by on Aug 28th 2016

    This makes the crx install much easier

  10. Have to have it for that one job 4 Star Review

    Posted by on Feb 26th 2016

    Bought this tool for installing the FrX, worked as advertised, however getting out the front plug is a bit tricky, ground 17mm flats on it so I could use a wrench otherwise it would be 5 stars
