curious. ok, i work on GM vehicles for a living. After one reaches 100k you can count on the fuel pump going soon. sometimes they go to the higher miles, like 150k or so, but its going to go. Seems that a lot of [censored] cars go way beyond that without needing the fuel pump replaced. Curious about chrysler vehicles, like 2000 to the present, are they notorious for fuel pumps after a certain mileage also?

I worked on almost all foreign and domestic.GMs were the best for going and mileage didnt matter.Ive had them at 40K to over 300K.We had one Dodge van that had 500k when I quit the one shop.Still OE pump.Ive seen lots of all of them with 200K and still OE pump Been doing it for over 30 years Finally retired and glad I am.Rocky

so chryslers indeed will go way further on the oem pump than GM?

The big in tank fuel pump killer is running the car super low on gas or heaven forbid, running it plumb out of gas. The fuel in the tank is what cools the pump. No/low fuel and instant overheat. I drove said Buick and Oldsmobiles as company cars with well over 250,000 miles on them with no problem..... until I ran the tank dry.

Oopsie.

I know that running low or empty is bad on them but it just seems GM's are notorious for the pumps dying somewhere around the 150k mark or sooner and was wondering about chryslers with the in tank pumps..
Im asking because we are looking for a used higher mileage vehicle, 2000 model or newer. We usually get GM vehicles and the first thing i would do would be install a new fuel pump just to ease my mind knowing how they like to fail with this kind of mileage. This time thinking of a jeep grand cherokee, 1999-04 with the 4.0. If i find one wondering if i should go ahead and change pumps but if they are not notorious like the GM's are for burning them up then i wouldnt worry about it..

The only in tank Mopar fuel pump I've ever changed was the one we ran out of fuel with, more then once. I've driven Mopars with in tank pumps well over 200K. 1/4 tank, buy gas, no issues. Run dry, buy gas, plan to buy a fuel pump shortly.
My daughters 1999 Jeep has over 200K and as far as I know, the original pump is still going. Gene

Where do the fuel pumps come from? Fuel pump manufacturers. They aren't built by Chrysler. My Taurus experience with two of them was around 90K miles, my Chevy Suburban was 130 K and the cheap Airtex replacement pump still hasn't failed after another 120K.
My Dodge's pump lasted until the pivot bolt came out, but it was built in 1964!
My wife's Hyundai pump went 117K.
