ok, so i have been searching all over the web, what is this saginaw fitting that is supposedly on the fuel lines of tpi cars. i want to go from the stock 3/8 hard line to the lsx fuel rail, which i got a connector for the rail, but its -6 an. how can i adapt that to the stock thirdgen fuel line?

This might be what you're looking for, I think one is 16mm and the other is 14mm. I'm not completely sure on this but someone else might chime in here soon.
i'll post up pics if it'll help when the stuff gets here, but what i think i'm doing (in theory) is that with the above adapter threaded into the original thirdgen hardline right at the firewall, i can thread a -6 an line on to that. then i already have another adapter i got for the -6 an to the gm quick connector on the fuel rail. its a russell fitting at the rail, i can check the p/n when i get home tonight. haven't even looked at the tank yet though, i want to get the front end stuff handled before i make any bigger mess in my garage.
So if I'm understanding this correctly, those fittings are all you need to connect the stock 3rd gen fuel lines to the LS1 fuel rails? Or does your fuel regulator go in between the two?
i'm also swapping in the 4th gen tank, so the pressure is all taken care of back there. guess it'd be the same for the vetter filter mounted back there though. if you are running a regulater and a return line, you'd need to use the smaller adapter for the 5/16 return, then the same -6 an line and quick connect adapter. i am just running a returnless system.
the russel fitings for the gm quick connect to -6 are
640940
640930
And the two adapters you need for the stock third gen hard lines are
9894DBJERL
9894DBHERL
Hope that helps
Explain what the GM quick connect is please. I'm not sure what you're referring to.
To help you better explain the situation to me, I am using the stock 3rd gen tank with a bigger fuel pump, the stock 3rd gen fuel lines, the LS1 fuel rails, and an Aeromotive regulator.
Well the LS1 will only need one of the fittings I am refering to since there is not return. The quick connect is the connector that snaps onto the fuel rail from the original fuel line. The adapter has that on one end and converts that to a regular -6 an fitting or you can use a JIC fitting as well.

This is a GM quick disconnect fuel fitting and connects to the LS1 fuel rail, this particular one from Russell has 6 an threads.
