Either way, with the hard lines on or off, it is nice to prevent fuel from entering the engine if they are on, or dripping over the engine compartment if they are off. If you use the junction box just forward of the battery, you can do an easy compression check all by your self, and since the ignition switch is in the off position, you should not have any fuel to contend with. People have difficulty locating that junction box, but it is just forward of the battery on top of the fender, has a cover to open from one end, and the little box is long but narrow. With a needle nose plier you can jump between two of the three screws to get the engine to crank. Try this jumping thing first, before the compression test to get a feel for it. Yes, you often see sparks fly. That is OK, and it is safe to do.
