Loud fuel pump... gotta replace it - it's too loud

I've tried a few locations - now low on the side of the skid plate - MaxBilt (very heavy/thick). The pump is mounted on rubber pads, straps are rubber lined, and the pump is wrapped in close-cell foam. And, it's louder than the engine/exhaust.

I talked with an MSD support tech who said "That's not a problem. It's just loud." I said "It's louder than the V8 and the exhaust. It sounds like an alarm is going off." He said "Well, the MSD 2225 is a loud pump" I felt like I was beating my head on a wall. I had determined that much.

I don't mind a little bit of whine, but it's just past the obnoxious db level. It's got to go. Could anyone suggest a replacement - a quieter pump?

Thanks!
 
I'd say something else is not right, like mysunnshine mentioned. I have an eBay special external pump in mine and once the engine is running you'd never know its there and I just have a 4.0 and very mild exhaust.

Cj8lvr/Jake has my original spare in his Jeep and I think he'd say the same.

I'd have to hunt through email to find the seller/model, frankly it's a cheap one that I got two of thinking its dead simple to swap out if it goes, but I'm still on my first one.

I use the pump that Hesco sells with their MPI kits. The only time you hear mine is when you first turn the key on, after that, you never hear it. The Hesco pump looks similar to the Airtex pump, but the Hesco pump is silent. My pump has been on since I installed the MPI a few years ago/10,000 plus miles, no problem:thumbsup:
 
I just replaced my fuel pump about a month ago. It was from NAPA and it was loud. The replacement came from NAPA also but it's very quiet. The replacement is slightly different than the old one, but I think it's made by the same company. The box is my barn so I can get the model info if you want it.
 
I have an inline fuel pump with my Howell TBI setup. The original Carter inline fuel pump became very loud after about a month of owning the Jeep. During my build I replaced it with a Walboro 255gph pump purchased through HowellTBI.com and it is quiet as a mouse. All I can hear(if I am laying under the Jeep and next to the pump) is the pump priming the injectors for startup before the engine is running.

Walboro's are good pumps if you are still looking at in-line/external
 
The Walbro pumps are the popular choice for LS swap guys as well. I may run this with my set up.
 
All of the pumps are good but none of them like to suck uphill out of the tank and then get introduced to heat.
