Fuel Line Solution?
So I am swapping in a L67 in to my 89 Lesabre T, but one of my many issues is the fuel lines. Mine come up on the driver side go up and hook a hard right to the pass. side to connect to the fuel rails on each side of the TB basically. As you all know the L67 fuel lines come from the rear and connect up by the */C. My question is what would you guys do about this?

There'* one new bit of information that should be mentioned. Literally been discussing this in the last couple days.
The connections from hardline to AN are rated for ~50psi. our fuel systems L67 will bump pressure to about 60-65psi at WOT. SWagelok makes connections from hardline to -6AN. No lie I literally was on the phone with my local distributor about 10 minutes ago.
Part numbers are:
SS-500-6-6AN ~$23.50
SS-600-6-6AN ~$13.80
They are rated for about 300psi if I remember the spec sheet correctly. I'd hit up www.swagelok.com and find a distributor in your area for the parts.
Beyond that the rest of the writeup is basically the same as mine. Although if you are using aftermarket fuel logs you can skip the connections to the rail and usually hook directly to the logs with -6AN

Those are threaded lines where they meet the rubber? Take a further look under. Typically GM would run metal lines and then add a flexible section somewhere near the motor to account for rocking and normal movement of the engine.
if you went Swagelok/Summit parts, you could find the possible metal and go from there...or determine the thread and fitting, choose to replace from the rubber up and just put the right fitting on the end of the SS braided line to replace the metal.

did I already give the Swagelok part numbers?
I'm not planning on swapping mine w/o seeing or noticing a fuel issue. I'm keeping a close eye and willing to take the chance.

If you took those apart successfully and determined the thread, braided or even black hose with whatever connection type you needed/wanted would be available.
