Is this a difficult operation? Does it take any special tools/equipment (I ask because it is a pressurized fuel injected system). And do you have any experience with Precise Auto Parts?

Thanks!

Pressure is relieved by removing the fuel pump relay with the engine running.

What about after the install? Does the system need to be re-pressurized and is there any special tools/equipment needed for this?
Thanks!
