What type of fitting connects the fuel hard lines to the rubber lines from the engine? Do they push together like the 4th gens or are they threaded? If threaded what thread? Thanks!

They are threaded, no idea on the size off hand though.

Thanks gearhead...that helps

they are saginaw fittings. metric o-ring. I think the thread is something like 14mm and 16mm, but i'm probably off a bit.

if you look up adapters for fuel lines from any of the AN supply type vendors, you can easily find the thread size and pitch.

pep boys etc will also sell short sections of replacement fuel lines that have those fittings, in case you need them.
