I forgot, off my head is it 5/16 ? Trying to replace all fuel lines on one of the FD.

I know I need Fuel Injection lines, just not sure about the size, yes I did search but for some reason nothing comes up.

 

its metric, 8mm

 

8mm but 5/16 works

 

Thx guys, I think 5/16 is close enough and probably the only thing we can find in the states

Another question about the hose we supposed to use, yes I know about the Fuel injection, was gonna talk about the Standard

the J30R9 standard is really old, I know it works, I know it's still available, but my point is with the ever changing Gas Formula (more and more bs added to it), shouldn't we move to something better ?

and after digging this for a bit, it seems that there are new standard (obviously) which works a lot better than the J30R9, found something from Gates that exceeds J30R14T2, they claim that it works with all systems even Fuel injection, with a working pressure of 225 psi I think it should be ok. Anybody tried these newer hose for their FDs?
