    fuel line adapters

    Anyone know of a company that makes a fitting that converts a GM o-ring male fuel line to AN?

    oh, are those TB fuel fittings? Can't tell from the pic. Cut the steel line behind the nut and put an -AN compression fitting on the steel line.

    If you want to do it the right way cut the fittings off and use the flareless MS fittings very simple and rated at 9000 psi!

    Well, I didn't like the idea of using compression fittings on the fuel line. I ended up buying the FI to an fittings and running new hoses from the fuel filter to the rail and the union on the the return line up to the rail. I used 491962 & 491962 from fragola Fragola Performance Systems And their push-lite hose to make the new lines. It came out nice. I'll take pics if you guys want to see
