You can get these . They are compression fitting on one end and hose barb on the other. The plastic line will shove on the barb (takes some grunt) . I use them on EFI all the time.
As long as you have the short metal lines for the Throttle body, you can put them on the line after cutting the one end off.
I have used these and other styles of hose barbs on EFI systems along with the nylon line. It works very well.
Be ure to route your lines safely away from exhaust heat and moving parts.
