Fuel Pump Life

I have a 95 3.8L Windstar which just turned 98K. Can anyone tell me the expected lift span for the fuel pump? Has anyone noticed an approximate mileage which they tend to fail? Please let me know.

I still have the original on my '96 at 183K miles.
One thing that you can do to help the life of the fuel pump is to avoid driving around will little fuel in the tank....
The fuel in the tank serves to cool the fuel pump....helping it last longer.
So....it is a good idea to fuel up whenever the tank gets down to 1/4 tank.

Hello Wiswind,
Thanks for the information. I've never own a ford before but have had several foreign autos. I've always have gotten between 100K-125K so I was wanting to replace both the pump and relay before they failed. Be nice if others respond so we can arrive at some average number of miles to failure.
Thanks

Owners of newer windstars report problems with the fuel pump relay.
In your case.....and mine....the fuel pump relay is inside the Contstant Control Relay Module (CCRM)....along with the radiator fan low and high speed relays, and the A/C compressor relay.
I have replaced my CCRM 2 times.....once for problems with the radiator fan operation, and 2 weeks ago for problems with A/C compressor operation.
I have not read any posts about problems with the fuel pump relay in the CCRM....just for the newer windstars where it was moved into the engine compartment "Power Distribution Box".
They did come out with a newer CCRM with a better sealed fuel pump relay.
The problem with the old style was that moisture would get into the relay....and in below freezing weather, after running the engine for a good while......it would not re-start after being shut down for about 15 minutes after being run for a while.
The improved sealing solved the problem......
I have not read any posts about the issue...but came across it in my reading.
One thing worth note......as I mentioned in the General Windstar Information post.... The OBDII system on the windstar does NOT monitor fuel flow or pressure in any way.
What this means.....is that if there is a fuel system issue.....such as failure of the fuel pump.....weak pump....etc....There will NOT be any code to indicate this......any codes would be from some other sensor being unhappy with what it is seeing.
So a common issue would be hard starts, stalling...etc....but no codes set.
Although.....several things can cause that (Idle Air Control....etc).
This is why you will find posts of fuel flow / pressure problems (like that relay in the newer windstars) that cause so much frustration in tracking them down.
I have also experienced dirty fuel injectors causing misfire and lean codes.....which.....took me a lot of messing around to figure out that a good cleaning of the injectors was all that was needed.
