Hi Mike, welcome to the forums you will find a wealth of information here.There are several ways to wire the pump including using a bosch relay and a standalone switch. The website I posted is only one way to do it. You need to know the amperage draw of the pump to see if it needs a relay and wiring it through an oil pressure switch means you'd have to have oil pressure for the fuel pump to work. Check with the pump manufacturer for more info.
Here is a website that should answer your Question.
