When installing my engine I noticed the fuel fittings were not working as they should so I lock wired them as an added precaution. Think this will work?

 

Personally, I would replace those.

Been doing some research but can't find the answer. My fuel rail supply is 3/8" which is 6AN i believe and the return is 5/16" which is 5AN. My question is: will the Russell fitting 644123 fit both lines?

 

The fitting will not fit both lines, but they make a fitting for each size.

Thanks! How did I miss that? Explorer has become just about useless on my computer with overprints, crashes and deletes.

 

The black versions of the fittings with the part numbers:

I bought the orginal Russels, then the threaded ones, and finally got the EARLS. I'm DONE with Russel.

 

Those are the ones that burn cars to the ground. I would never use the adapters with the plastic clips...

Russell makes threaded conversion pieces, which is included in the link.

What are the PNs for the Earls threaded 3/8 & 5/16 ends? I cannot find anything in their FI section except quick connects with retainer clip, mimic of factory retainer...

I agree, skip the plastic fittings.

 

See if this works
