I want to replace the rubber fuel lines from the hard lines on the fuel logs to the hard lines to the frame.

need to know what AN size they are....don't want to take them off without the replacements on hand....one is about 16 inches long, and the other is about 12 inches long and need a wrench to take them loose.

thanks

 

It's hard for me to believe that with all the show quality cars on this site, no one has replaced these 2 rubber lines, that connect fuel rails to the main lines.

some help would be appreciated

 

I believe that the lines are 5/16" and 3/8 inch (should still double check). 5/16" would be -05AN and 3/8" would be -06AN. Chart here.

I replaced mine years ago with Aeroquip stainless hoses. I cut the fittings off the metal lines at the frame, flared the lines and used AN fittings and hoses all the way to the fuel rail. (Beware, AN fittings use a 37* flare, not the normal 45*.) I purchased a -05 to -06 AN adapter for the return line and used -06 hose for both the feed and the return. Accel used to sell the required Saginaw to AN adapters for the fuel rail. If Summit or Jegs don't have them, you may be able to purchase the adapters from Street and Performance.
