Installing the new fuel pump in the pickup assembly for a 92z L98 and ran into a little dilemma. The stock setup had this thing connecting the pickup tube to the fuel pump, and was wondering if I should re-use it or use the supplied rubber hose instead. Fuel pump kit is from Racetronix, and I emailed them aswell.

I believe that it's called a pulsator. It's a rubberized chamber that I believe is there to absorb shock waves created by the injectors opening and closing in a batch. Last time I changed my pump I didn't put it in, next time I think I will just to see if it stops the fuel pressure gauge needle from vibrating like it does.

Yes, it is the pulsator. It's not needed, neoprene hose will do the job.

throw that out and use the hose, pulsators start to leak eventually and are useless
