Default Quick fuel pump question

Ordered a new fuel pump/sending unit (the whole thing) for my 94 LT1. It did NOT come with a pulsator, but instead a piece of hose to directly connect the new pump to the fuel sending rail. Is the pulsator necessary, or is it ok to connect it directly? Judging by photos on parts sites of fully assembled sending units, its seems 50/50.

Thanks for your quick response!

Get rid of the pulsator. Use the hose and call it a day. That pulsator has been known to leak with age. Nothing seems to get better with age so dump it.

I ditched my pulsator. It's supposed to smooth the pulses put a bit in terms of NVH, but I noticed no difference other than one less place to lose fuel pressure.

I'm told wine does. I cant say I'm a wine guy, but i can attest that beer does not get better with age.

However, the vast majority of wine is not aged, and even wine that is aged is rarely aged for long; it is estimated that 90% of wine is meant to be consumed within a year of production, and 99% of wine within 5 years.
Experts vary on precise numbers, but typically state that only 5–10% of wine improves after 1 year, and only 1% improves after 5–10 years.[
