As others have said, relieve the pressure with the proper procedure or seek professional help. The fuel system on those common rail engines is extremely dangerous. Fuel pressures are so high, they can slice through flesh and bone if not dealt with properly.

That's what I'm looking to avoid! I just realized that I forgot to check quickserve for the procedure so I'll go through that too.
