valve sizes and tank port sizes

hi everyone im making my own airide setup and i have a question if i have 8 3/8" valves does that mean i cant buy a tank with 1/2 inch ports??????
or does it have to be 3/8 valves and 3/8 ports
1990 mm
2.4l 4cyl
2wd 5 speed

you can use any size ports you just gota get a fitting to step it down from 1/2 to 3/8. assuming your running 3/8 air line too.

i use 1/2 inch air line with 3/8 valves, just get the right fittings.
