Bolt On Fuel Pump

Trying to get this bolt off of the fuel pump.

Used two wrench to counter turn in attempt to loosen the hex bolt at the bottom.

Is this correct?

Not sure if it's not loosening up because it's locked up or if I'm doing it wrong.

Loosen the top bolt for the pipe. Use penetrating oil too.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

For now hold bottom one stationary. Turn top "B" nut counter clockwise. Remove the fitting and tube. Remove the pump. After you've removed the pump you can easily remove (counter clockwise again) the remaining fitting in the pump. As wbain said, use penetrating oil on the fitting to make the job easier. Before reinstalling fittings on new pump inspect for galling, thread damage, cleanliness, etc.
