89 k1500 and I'm replacing my fuel Line.

I am replacing my fuel line in my 1989 K1500. I have never done this before and this maybe a stupid question. I know there is a lot of pressure in the lines, but is there anything I need to do before I start removing the old fuel lines. I am not sure if I need to do anything to the fuel pump to release pressure or not. I assume not, but just want to make sure. When I put on the new fuel lines is there anything I do to prime the moter or just let it crank. Thanks A lot

no need to releave any presure. the tbi unit releves the presure itself. just crank it when u put on the new fuel line.
