Fuel Pump Preventative maintenance?

I have passed 250,000kms on my S430 2004. Can someone shed some info on the life of the fuel pump on these cars.

On my ML320 cdi at around 257,000 kms my fuel pump gave up on the highway in winter. A simple job which I could have done and cost me around $600 ended up costing me 2.5 times.

I am doing a lot of highway 1400kms per week, and don't want issues on the highway, so wanted to know if I should just replace the fuel pump, but then I just don't want to throw money

Car has been fine with about 40,000kms put in the last eight months with only oil changes along the way. Sure it was winter and hate working on the car in winter, but will look under the hood now that it is summer.
