What you have there is an extra O-ring. I've used that method to fix leakers before.
Just a word of caution, you have to advance your pump to compensate for the G codes cause they have a higher pop off rating. Something like 15% more advance (if your set at 8* BTDC then you would have to bump it up to 9.2*...thats the basic principle).
