Editing Fuel Injector Replacement (section)

== De-pressurising the fuel system:==

This I say is an optional step, but I'd recommend it to people who don't have experience with this or are more cautious. Remove your fuel pump fuse and crank the engine. Repeat this a couple of times and you're pretty safe. Needless to say, if you undo all fuel lines slowly and carefully, you shouldn't get sprayed.

To disconnect the fuel supply and return lines you just need a Phillips head screwdriver and undo the clamps at the rail. You may need to twist, turn, pull or pry to get the hose off. Any cracking, splitting or fraying hose should be replaced with appropriate high-pressure fuel hose & quality clamps. In case there's any confusion, your supply line has the fuel filter on it and the return nothing. Return is always the lower line at the fuel rail.
