what is the mm and thread pitch on the fuel filter /hardline connection (93 3.0)? I want to convert the hardline from the filter forward and the return line to braided line in order to re-route them further from my pass side down-pipe. Thanks.

 

14mm1.5 -- got it . thanks.

Why are there 2 return lines???

 

Only one is the return line the other is to vent fumes from the fuel tank back to your charcoal canister.

 

Yep, got it. Thanks for the follow up T.D.
