You can release some of the presure at the valve on the fuel rail.

When I pulled my engine I was able to leave the fuel rails in the engine bay as I did not have the tool to release the fuel line from the rail.

Plus I new I was pullin the whole full system out as well as the tank.

Anyway, even after purging the system at the fuel rail there was still presure in the system.

When I pulled the whole fuel system I left the gas cap off and pulled the return part of the system first.

Then when I pulled the supply side I found the left over presure.

It was not that much and hardly any fuel came out.

As I recall the shop manual had a process to eliminate all presure in the system before disconect.

Hope this helps.

Then Take The Fuel Cap Off, IT DOES MAKE A DIFFERENCE!!!! I Recommend Putting A Towel In There, DONT FORGET TO REMOVE & REPLACE THE CAP BEFORE STARTING!!!!
