That is just the NPT fitting size. You can use the 1/4"npt to 3/8" hose fitting.
Just be careful not to get too much pump and have a PSI problem.
Also, just for comparison... a typical garden hose hooked up to your house flows about 25 gph at 40 psi. Your looking at pumps that flow 80 gph or 110 gph and only needing 5-7 psi...
A stock GM Mechanical fuel pumps only flow 40-60 gph. I am betting the 80 gph will do just fine.
Holley wouldn't build a pump with fittings that were too small and kill its output.
