How do you remove stuck fuel pump rod on 89 Chevy 454?

Today I removed the fuel pump push rod from my 1985 305 Chevy V-8. It was stuck so bad that it has taken ten months of trying every thing I could think of to remove it. The rod is 1/2 inch, so I went to the hardware store and bought 1/2 inch copper tubing and a copper "T" connector, plus a bolt with a 1/2 inch hole. I also purchased J-B Weld epoxy metal weld. I glued the "T" section to a ten inch long section of copper tube, than I glued the bolt with J-B Weld just above were the "T" section is glued to the tube. I cleaned the stuck fuel pump rod in the engine block, than put J-B Weld inside the top of the tube, being careful to keep the weld in the tube so it would not glue the copper tube to the engine block. I inserted the copper tube (with the J-B weld glue inside) over the exposed fuel pump rod (making sure to not touch the top of the copper tubing to the engine block). I let it set for 24 hours. Next day I insert a new fuel pump rod in the "T" section of the copper tubing and twisted the fuel pump rod around and around while I pulled down on it. It took about 5 minutes and the old fuel rod fell out. I was amazed this J-B Weld was able to bond like that. But my 10 month nightmare is over. And the new fuel pump rod goes in tomorrow after cleaning the shaft with a wire brush and cleaner. Than I plan to put plenty of lube on the rod. Be sure the bolt at the front of the engine is backed off (it contacts the fuel pump rod). The bolt on my engine is the upper bolt holding the alternator bracket.
