My fuel pump makes a groaning/whining noise pretty often, when the car's on. i've come to the conclusion that i need to replace it. which fuel pumps are good? does it matter which one i get?? I found 2 or 3 that i'm trying to pick from, any advice is appreciated...

here is the three that i found..the ones that go on a 93 z28 5.7l
