The fuel pump has become noticeably noisy, how long before failure do you reckon?

 

When I bought the car I thought the wheel bearing was slightly noisy, garage said not to worry but carry on until it got really noisy, 25,000 miles later it's not got any worse. 

 

Should I change the pump, there are some cheap units on eBay or s/h ones locally, it doesn't look to be a difficult job?

Check that the filter screen on the pump isn't clogged first, then change the fuel filter itself, if the pump is still noisey then you can change it.
