    I have a 1970 RoadRunner with 440-6 engine, they list two fuel sending units.

    One with 68-70 B-Body with 3/8" fuel line and 1/4" return line

    the other 68-70 B-body with 5/16" fuel line

    which is correct? Thanks

    It's the 3/8" line. All 440's and hemis had the 3/8".
    That said, good luck finding a good reproduction sending unit. All of 'em are
    Chinese and they blow dead bear.

        I have gotten 2 from Right Stuff one for the 68 R/R and one for the 73 Duster. Prepare to be dissapointed.

        Got mine from Advance Auto 2 1/2 yrs ago. Made in China. Had to work on retaining ring to make it fit properly. Still working perfect. BE SURE ground are correct.
