Going...going gone!
Replacing the fuel pump (standard Delphi), sox and fuel filter. Appreciate some "been there done that tips." Looks fairly straight forward in my FSM. Considering my Lt1 is 14 years old ('94 w 140K on chassis) this is a preemptive move. In retrospect should have done this back in Aug when new eng and ZF 6 were installed. Considering the fuel tree has been submerged a long time
I plan to cleanup all electrical connections and give the float mechanics a cursory inspection. Whats an easy way of relieving fuel pressure without spraying high octane in your face?

It is easy. Pull the FP fuse and start the car (if you can) should relieve pressure. Pull the boot out disconnect the wiring disconnect the lines un bolt the 10mm bolts and pull out it takes a little twist as you get to the business end. You may need to replace or eliminate the pulsator probably it is a rubber pressure equalizer to smooth out the flow/noise just in front of the pump.

Thanks gents...looks like a piece of cake!
Got the gasket...haven't pulled the tree yet. Received a neat 15 page installation manual from Blowerworks.net Good clear illustrations.
With their high capacity Walbro pump they recommend eliminating the pulsation damper. Don't want to introduce flow and noise issues. Corvette had a good reason?? Will check my Chevy dealer for the bad boy. Disregard the dealer Auto Zone had it.

Well you WOULD think they had a good reason, I tend to follow that line of thought usually as well, but there are SO many things the manufacturers are asked to do due to regulations for emissions, sound, the list goes on and on.
That being said, I think GM is one of the few companies that uses the pulse dampener, I say get rid of it. I did with no problems and lots of guys on the Forum do as well - you won't notice a difference in sound and RedEasy is right, it's a source of future problems.
