Still original Water and Fuel pumps
My friend's car stalled w/o warning. Needed to tow it and to a garage for a $700 fuel pump replacement. Scary.
Mine are both original on my 98 Maxima 299,000 km or 180,000 miles.
I haven't experienced any stalling as yet, the usual symptoms of failure for these parts?
Is a good way to test or maybe I should change on my own now to avoid towing and exhorbitant garage charges when you have no choice?
I intend to hold onto vehicle some time more and they WILL fail some time.

I view this as a personal decision. The fuel pump will eventually fail, just like every other part on the car will. The fuel pump does not have a high failure rate, but it does fail. Your engine and transmission will fail at some point. Do you want to replace them now so that you won't risk being stranded? Being stranded is inconvienent to be sure, but it is rather expensive to replace everything "just in case". It's up to you which way you want to go.

you can check around the water pump and see if its sweating coolant at all. if youre due for the timing belt/chain (not sure what 4th gen have) just get the water pump done at the same time since youre already in there.
to save the fuel pump, never let it get below around 1/4 of a tank as mentioned, if you do grit and debris sitting at the bottom of your tank will get forced through the system

If there is any grit or debris in your tank, they will be at the bottom of the tank regardless of the fuel level.
The pump screen will catch anything to big for the pump to pass.
The fuel filter will catch anything to big for your injectors to pass.

This has always been my thought. The reason I posted about keeping over 1/4 tank is that the pump is cooled by the fuel. The lower the fuel level, the hotter the fuel and pump.

I changed my rad two years ago, but still have original water pump.
To extend longevity of the water pump, would Toyota Red of Nissan coolant make any difference? Always used Prestone.

yes, it would prestone has silicates to scrub and keep internals clean in American engines. Japanese autos dont use this, it will wear down parts slowly. our fluid coats the parts to protect them (takes a bit longer) thats also why you should change fluid when changing radiator.

After working for GM and VW, I will never use anything pink, red, or orange. Green only for me. The others crystallize in the jackets, and cause corrosion, no thanks.

Change fuel filter every 50,000, with aftermarket brand. Radiator has been replaced once. Coolant has been replace 2 times. Once by the dealer on the original radiator. Once by me on an aftermarket aluminum radiator, using prestone green coolant. But, I tell you the truth. I think what made the biggest difference was putting an engine oil cooler.

Holymoly,
Here's Stillen's oil cooler;

Manual transmission maximas don't really need them, but can use them. Automatic Maximas have oil coolers built into the radiator because tranny fluid in an automatics work way way harder than the fluid in a manual gearbox.

Yes, I use a Stillen Engine oil cooler. It doesn't have to be Stillen. As for Manual Tranny cooler, I have never herd of one.
Yes, Automatics do have a oil cooler built into the radiator. Which means that the oil will never get cooler than the fluid in the radiator. Hmm, something to think about.

Manual transmissions don't have oil pumps so a cooler wouldn't work any way. So auto tyranny cars have engine oil coolers? Where do the line connect to the engine? Sounds like a mod I would do along with remote filter.
