Default Newbie fuel pump issues

Replaced fuel pump and filter this week and the pump started making the noise in this video and died 2 days later so I ordered the same pump and it's making the same noise. Does anybody know what this problem is?

Like what was mentioned above, It would definitely help if you can tell us what pump you used, where you got it, etc.

Edit: what year is your Jeep? Can we have some more information?

Sounds like Delphi is junk. Bosch is the way to go.

But TBH, it sounds like the pump is working insanely hard to pull fuel. Did you replace the filter? If so, what brand?

I had the same thing happen with a Dodge Caravan, but that was because the tank was loaded with road crap because of a rotted out filler pipe. The Dodge dealer fixed it free after realizing what they had done. They replaced the filler pipe and pump WITHOUT CLEANING THE TANK! IDIOTS!

Dealership..... enough said

But I think we're on a similar page here. You can continue to throw pumps at it but if it's picking up a ton of garbage in the tank you're just going to keep frying them. Have you made any enemies recently? Ex's? Sugar in the gas tank will fry pumps over and over. Just ask me about the time a customer brought a suburban in that his ex dumped a big bag of sugar into........ oh and a full tank nonetheless

Sounds like mine. We bought ours 3 years ago and its been making this sound. Really annoying. Some one suggested to me it was the filter. But I got under the car with a rubber hose to use as a stethoscope and its definitely coming from inside the tank. We put about 10,000 miles on it since we have had it, so I don't think it is going to fail anytime soon.

Referring to the fuel pump strainer to be exact. This is mounted to the bottom of the fuel pump assembly. If it's clogged up the pump will be working extremely hard to pull fuel through it. A clogged fuel filter will do the same thing except the pump will be working hard to push fuel through it. You won't hear any noise from the filter since there are no mechanical/moving parts in it.

MAY be a dumb question so forgive me. But I have a 03 jeep GC 4.0 and I have wrenched all over this thing and I haven't seen a fuel filter like a in line type of sorts I know theres a strainer that goes on the pump itself but was just wondering cause I see all of post people say change the filter.

It's in a bracket above the rear axle with 3 hoses (plastic) attached with quick disconnects. The pressure regulator is inside it.

Ok so I replaced the Delphi fuel pump with a Bosch and the filter with an oem. It's still humming and dies. The sound is coming from close to the tank. Any ideas? I also blew the lines out, they weren't clogged.
