Fuel pump/filter caution to owners

Hey guys, i got a 04 4.8is

i bought it at 92,000km

the fuel pump always made a little bit of whining noise, never thought much of it

got a fuel filter cuz my gut told me to

filter sat around for 2 weeks and my pump started making more noise and no power after 5k rpm, slight hesatation at 1600rpm

pump blew over a course of 4 days ounce i hit 98,000km

new hella pump 308$ plus 12% tax

new pump was whining, this had me concerned, drove to work

2hours later i changed the filter

and vuala no more pump noise

my filter was clogged and cost me 500+ for a new pump and a tow truck

dont let this b U!!!
