P30 Fuel Pump Service Life?

I believe that replacing mechanical items when there is no indication of failure is a bad way to approach these things. If that's the case, where you stop? There are so many items that could be replaced, that you would be just as well to buy a new motorhome. Wheel bearings, water pump, CV joints, alternator, PS pump, electric fan motor, clutch fan assembly, and on and on we go. The replacement items aren't built as solid as the original items, so run them until they start giving you trouble and then replace them. Instead of throwing money away on replacement parts before they fail, purchase a good tow policy and sleep easy.

Happy motoring.
