How was the leak down? If it started easier with the throttle wide open, you have a leak in the plenum that needs to be addressed. But if you want more specific information, you will need to let us in on the secret of what it is you are driving...

ok thanks. Assuming I have a leak in the fuel line going to the injector, will i just need to replace the o ring or replace the whole spider fuel line deal?
