Fuel Leak Question

[realprore]

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

Long shot here, but are the o-rings you bought safe for use with fuel? Normal ones would just fall apart when the fuel is put to them.

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?

Just go to harbor freight and get a viton o ring pack...


Or if your feeling daring there is always kalrez...

There is absolutely no need for it when talking about cars, its basically chemically inert go look at prices then you will get the joke.

Odd Ford would use (6) o-rings??? Done mine before for a pump swap and never noticed that. I thought they all were the Brown monster o-rings (1) each per connection.

This is from LMS.. maybe you should call & speak to them?? They also carry the factory line to the front for crazy money... Seems your not getting the correct size o-ring. These are the front ones... seems the back would be the same.
