Nope, it specifically states that the Lifetime warranty isn't in effect for this item. But, i can't see where it states any warranty period. i wouldn't want to get one that died in a short time, as opposed to having one with a known warranty.

Brushed motor. Will read a few Ω if functional. Definitely motor bad. How many miles Odom? What's your average mph (from dash).

(I collect this data for the next guy)

Not too surprising. I needed one fast and bought an Amazon special for $120. Lasted 11 mo. but the Warranty replacement lasted years until we sold the car.

"pay once, cry once" vs. "pay, and pay again, crying all the time" parts buying
 

Heck, back before I retired, with the ability to work as much overtime as I wanted, price was not an object for my automotive projects and/or my race car. Having 5x the income was nice.

pump ordered, prparing to remove bad one
 

I vacuumed and cleaned the area, so nothing will contaminate the fuel. Took a photo of the extremely aged-looking top of the pump, and it has a reversed BMW logo and part number barely visible...might be oreiginal to the X5? I've got a '98 GMC with a 21 y.o. pump installed (I did it myself, so I'm sure of the age), so 24 years on a BMW pump might be achievable.

Then, I ordered the Hella pump assembly from RockAuto. It should be here in five days, so I can have all my tools and parts gathered and ready for the job. I can't find my brass punch to loosen the sealing ring, my hose-gripper pliers, nor my kit of small clamps (both worm gear and spring clip types). It looks like my garage Poltergeist has returned, or am I just getting forgetful?

I've had good luck with the Hella parts choices I've made. I'd go Hella for this one if it were me.

I just saw 80'Stech's Delphi thread and while I didnt have the mismatching pump size problems when I got a pierburg, working on an old sender there was the feeling something would just crack or break off.

I've not experienced burnt sockets but the insulation breaking off on the bump harnesses I've seen (both MB and BMW's) seem like they could be a cause of that kind of a problem too.

EDIT: I see you got the Hella. I'd suggest a fan for ventilation to add to the preps. Working in gas fumes suck ugh.

I prefer to muscle the ring off rather than hit it with a punch/screwdriver.

One message I used was taking some flat bar stock 1/8 by half inch and bend it into a U shape upside down.

hook that onto two of the little bumps on the ring and put any long bar like a breaker bar between the two ends and turn.

I made a custom tool out of the bar from an old Quicke clamp that I just put a big wrench on and turn it off.

that said every YouTuber just uses a screwdriver and a mallet.

Your mysterious fuel trims might have an explanation. The pump my have been dropping pressure while hot and running. Let us know how you like the Hella pump. Mine is due for one too. 170k miles is really pushing it.

Reset the fuel gauge with test 21.

Not familiar with this and it's effects, what does it do?

Hope it improves gas mileage lol!
