More like pressed in. alot of spray lubricant(i.e. liquid wrench, pb blaster). Just be careful not to snap it off in the block, or you'll be trying to find a way to tap it out.

I've mentioned this before, if the base doesn't look to bad, you can cut it across about 2in above the point it meets the engine, and then cut the new tube the same length as the newly removed piece, minus an inch, get you some fuel line 2in long, 1/2in down and 1/2in up; if you can still put the bolt in, then the tube is the right length and the stick will give accurate measurement.
