Relays are used or required for electrical devices that have unusually high amounts of input or steady state current. If you plan on designing circuits to run pumps and motors and will not be using relays you better use some herkin big gauge low impedence wire and keep several charged fire extinguishers handy. The primary reason why relays on pumps and motors fail is because they have a serious job to do in terms of switching high current loads. My best suggesiton would be to get a catalog or go a website like Newark Electronics and spec out a higher end relay. You can get some really sweet ones with gold plated contacts that will probably outlast the crap that Ford specd out by 4 or 5 to 1. The downside is they won't be cheap. I see that several aftermarket guys are offering solid state panels now. The downside with them would be repair if there is a failure. Good Luck!
