Huh?

If you're putting a new sending unit in it, you should have all the new parts.


the only thing i don have is the pulsator that goes on inbetween the sending unit an the pump which is all in the tank... its a lil black peice that has two opengins one to slide on the sending unit and one the that pump slides in... but the housing on it is all cracked and i had some running issues with it on how it ran before so i don know if that was part of it the problem but the part is like 90 bucks which i don really have right now so i wanted to know jus to get it up and goin so i can atleast moved it for right now if it would matter if i deleted the pulsator thing for right now

The new pump should come with a short piece of black rubber hose, this goes in place of the pulsator.
Rule of thumb: never replace the pulsator, they were a junk design and are always known for leaking and causing problems. That is why you didn't get a new one with the pump.

Sidenote: The job of the pulsator was to quiet the fuel delivery system, that's all it was designed for.
