Assuming it's a mechanical fuel pump so no good looking for a fuse to take out. Is pulling the fuel line off the carb going to be the easiest way and redirect. 4. Fuel related misfires can be caused from incorrect atomization of fuel. One of the most common symptoms of a clogged fuel injector is a rough engine idle. I don't think removing the hard lines is SOP for a compression test, but if it makes your life easier, go for it. The pictures I've seen make it look like the best thing to do is disconnect all the hard line connections at the injection pump and at each injector, and lift all the hard lines off the engine as a unit (leave the rubber vibration dampers attached to the lines).
How to Test Fuel Pressure with a Compression Tester. Yes, you can test fuel pressure with a compression tester. In fact, using a compression tester for this purpose is a great way to save money and time.
