170k
Wait until I break down, or replace now?

 

What about the main bearings? The freeze plugs? The ECU?

This is the life of owning a higher mileage vehicle. There's no way to know how long something will last, and preemptively changing parts isn't worth it. Keep a tool kit with you and maybe bump up the insurance to include towing.

 

^^ yep, I'm at 240k, just had the fuel tank off and debated putting a new fuel pump in.. decided to wing it

 

What they said. Some go 300k. Some go 150k. Age, quality of fuel, lots of variables.

 

I have an 01 XJ all original equipment with 226K on it.

 

And the crappy replacement parts rarely last at all.

 

see if you can locate a remanufactured OEM replacement and they are a bit better than the junk from China parts

 

I believe mine is original 301K miles. keeping contaminates out of the tank can improve the life of the pump.

 

I'm selling my 2001 XJ bc I want something different. Preferably a sports car like a mustang. May even trade for a mustang

 

Ain't that the darn truth....

 

Some people are "old school" Jeep people...and some aren't... I would say this... if you enjoy your XJ.... cool your jets for a bit and give it a little time....
For me, I love my old XJ even though my wife would sell it if she could... It has always gotten me from A to B... road or no road... hauls most of what I need.
Many parts still readily avail even though the last one rolled off the line 2 full decades ago. And it's an older design that you can wrench on yourself without needing tons of high $ diagnostic equip.
So factor in wants vs. needs before you hop onto the next vehicle and then end up regretting the sale of the XJ....as those are harder to find in solid clean condition.

Just my 2 cents and years of vehicle purchase/selling experience.

 

I appreciate your input as to the sale/trade of the XJ, I have rebuilt this XJ from the time of 1/1/21, to current and it doesn't matter what I replace it says it is bad 4 months later when I fix something else that's connected to the original causation of problems.

 

Ya know... most people will just get whatever fuel pump they can get at the local parts store and it will be crappy enough to where the 22 year old one with 170,000 miles outlasts the new aftermarket replacement.

If you're going to do it, go with a Bosch, Denso, Delphi, etc brand of pump. A brand that you actually heard of who actually exists and makes OE parts for manufacturers even if it isn't THE oe manufacturer.

I think the originals that Chrysler were using back then were Walbro pumps.

 

97 and up were Bosch. I got one to install just waiting to get time to do it.

 

I bought an O’Reilys fuel pump when my seal was leaking just to be “preventative”. It was a Precision brand and the check valve failed right out of the box. Would not hold pressure causing hard starts. Had to do the damn job twice. (I hate fuel related work) I did a little research and found out Bosch was OEM for ‘00 and found them on Rock Auto for $40 less than O’Reilys. Perfect pressure and hold pressure for 30 minutes after shutdown.
I will only use Bosch in my XJ.
