How do you change the fuel pump in a 1983 camaro Z-28 wcrossfire inj?

Just had mine done on my '83 Z28, and highly recommend you take it to somebody professionally and let them do it. Being that the pump is in the gas tank, that is bad enough. However, the garage that did mine stated he needed to move the stock exhaust muffler system. Being that it was rusty, he needed to cut it and re-weld. Not to mention, he also needed to swing the rear axle out of the way, in order to lower the gas tank. So, unless you have lots of time and patience, I highly recommend you forgo the hassle.
