Pulsator in Fuel Tank 96 Chev 1500 PU with 305

I am in the process of replacing my in-tank fuel pump in a 96 Chev 1500
PU with a 305. I noticed the fuel pump is connected to the line via a
"pulsator". Should I also replace the pulsator? It seems likely that
the fuel pump may have been ok, but the fuel could have had an internal
tank leak via the pulsator? The truck would not start if cold, idel
once once stated but if rpm rasied to 1000, then would cough. If
brough back to idle, would run ok, if continued to raise rpm would
stall. What is with the pulsator? I find it had to believe it will
hold in 50 or 60 psi the way it fits together. (I replaced fuel filter
and ran with air filter off)

Yes, replace the pulsator as long as you're in there.

Does the new fuel pump not come with a short piece of
hose and two clamps? We don't re-install the pulsators
anymore, we just use the hose and clamps that are
supplied.

I left mine off, used the piece of hose, and it works fine. Which makes
me wonder, what the heck does the pulsator do?

Yes, I did get a piece of hose and two clamps. I assumed they were for
another type of vehicle with a different set up. I will install the
hose and leave the pulsator off.
