Holley Stealth Ram Fuel Fittings

[Dog House]

Can anyone tell me what they used to connect the HSR fuel rails up to the stock fuel connectors? I know it needs to be an inverted female fitting but I’m having trouble finding out what size and thread the stock connectors are? Thanks

There an instruction manual for the HSR online. Looks like the inlet & outlet are -6AN fittings. I've seen guys run the feed line starting at the fuel filter, which has a saginaw fitting, to the regulator (-6an). You'll need some adaptors so check out the fuel plumbing manufacturers like Earl's. They have online catalogs.

16mm Metric O ring

For a rear entry fuel rail most run new -6 AN lines up over bellhousing from filter area and do away with the stock rubber lines through engine bay
Need -6 to Metric O ring adapter to join new line to fuel filter and return line coupling


Check before ordering ;
some years had a smaller 14mm fitting on return line
