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.

Fit was perfect, well thought out design

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.

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.

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!

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.

This makes the crx install much easier

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
