TR6 yes, TR3A no.

TR3A for sure.  I'm not certain about TR6, but I think it continued the
usage of 1/4" line (od for hard line, id for soft) from the pump to carbs.

The interesting bit is the pump outlet, which is sized for 5/16" line.  They
used a special adapter nut in order to put 1/4" line into the 5/16" port.
