Fuel Leak Question

Hey everyone - I have a '94 GT with a leak coming from the fitting (pictured) attaching the fueld pump to the pressure line. It was leaking (spraying really) dramatically. I pulled it apart and found 6 o-rings (2 large, 4 small) three of which were badly deteriorated. Figuring this was the problem, I jumped over to the parts store to find new o-rings. I replaced all 6 and it still leaks like crazy.

So, I have 2 questions:
1. Does anyone know the size of these two o-rings? Are they metric or standard?
2. Is there a particular order or method to installing them and putting the fitting back together?
3. Is there an alternative I can pursue if this won't work out?

I called Ford - they said they never sold just the o-rings, and don't sell the line any more.

Thanks,
Jon

It's possible I suppose, but they are still intact - it started leaking again immediately - it didn't work for a while then quit again. Where would I get fuel specific o-rings?
