280z fuel tank hose sizes question

[fairladyz432]

My 1975 280z fuel tank feed hose needed to be replaced and i think the size according to a number of sources say its a 7/16 fuel hose for the feed side that goes to the fuel pump. However, im trying to figure out how to go from a 7/16 size fuel hose to a 5/16 fuel hose that goes to my new electric nismo carburetor fuel pump. Any ideas on how to convert that or is there a reducer of some sort? Tried looking at some barbed reducer ones but haven't gotten an exact match.

Check Lowe’s they may have a brass hose barb that goes from 5/16 the 7/16. If not you can definitely build one from the items they have in the same plumbing section

checked lowes and dont have exact sizes but managed to squeeze 5/16 injection hose over a pre fuel pump filter so all i need to find is a reducer that will go from a 3/8 hose to 7/16 to the tank. THanks for help anyways.
