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..
