Fuel rail plug

Opposite corners on the head.... Need to remove the plugs. What tool should be used to remove these? Really don't want to strip them, just makes it harder to get out. Passenger and Drivers sides. My 8 mm socket and wrench won't work. Wants to strip them both.

It's a square plug so you can get the open end of a wrench on it. A small pair of vice grips will also help in breaking it loose so you can switch to the small wrench.

I've had good luck using a quality small adjustable wrench and lots of penetrating oil. A Harbor Freight special won't work, the jaws will spread and start rounding it out.

I used the "spline looking" socket from Craftsman on mine, I think it was the 5/16 one that fit. IDK if that's the right name for the sockets but that's what they look like & work great on square plugs. I also sprayed PB on the plugs for a couple days before trying to remove them.

Ahhh yes, good call. Those are some biting sons-a-b's, probably work real well.

Yessir they do, I was really worried about making a mess out of those plugs (I have that kind of luck) so those sockets were a part of my FRX expense & will be good to have around

If they're square you might want to try an 8-point socket if you can get one on it from that angle

They are out. PB Blaster and an 8mm wrench. Plus, a little bit more effort. When you work until 2:00am trying to get things done, mistakes happen. So, I picked up my tools and closed the garage door. Just about stripped the back plug. Have one more fuel line to install and hooking up the second pump left to do before testing.

I use a 5/16 square plug socket. If I would have been thinking I would have sent it to you to use.

Thanks Mark, I do have one more truck to work on. So, if you want, send it up. Not Ed's he's all OEM...

It was not the 8mm wrench, its a 7mm wrench. Finished the fuel system tonight. Will make some changes later on. 45 degree fittings for the front of the heads and straights for the rear. Will have to make some adjustments when the new turbo goes on, but its minor. Just about everything came off the top to do the work easier. Even the two eyelets for pulling the motor. I know someone who can make a pretty good eyelet dead center without the motor rolling....Rockrunner.
