You need these.
Fragola Performance Systems 491973-BL: -8 X 3/4-16 ORB BRASWELL CARB ADAPTER FEMALE NUT BLACK | JEGS
Carb inlet stand off.
Not saying this is the right size AN but you get the picture.
Looks like what i linked is -8 just order them in -6.
You will also need 2, -6 male unions or see if they sell the stand off in male to male?
