Fuel sender plug so corroded, one prong literally crumbled to dust. Problem is, phillips screws are really rusted. I got it soaking in PB blaster now, any tips from those that have tackled this before?
I haven't dropped the tank, hope I don't have to.

 

i used a vise grip to turn them out but before i tap them with a hammer to brake them loose. i got them out
and i went out with the old ones got new ones at HOME
DEPOT now my gauge works great. i did not remove tank for this

 

Mine were as rusted as yours. I was able to get a couple removed but I ended up having to grind the heads off the rest. Once the unit was out I was able to clamp a couple of the studs with vise grips and turn 'em out. The remaining ones I drilled out then chased the old threads with a tap. It was a royal PITA to say the least but it all worked out in the end. Good luck!

Crap, I was afraid of that. Just filled the tank up when it went out, too.
Thanks for the help!

 

That is the key and the tip of the day.....
