On a factory firebird or camaro with a carbed V8 how does the fuel line(s) run under the car up to the engine? Anyone have pictures?

I don't have pictures, but could get them in about a week or so.

The lines come up the driveshaft tunnel on the driver's side. They pass over the transmission to the passenger side, up the frame rail, to the fuel pump.

Note the plural. The supply and return run side-by-side.

It's a horrible set-up, exposes the lines to a lot of heat.

The heat of the exhaust headers is what I'm trying to avoid most.
Routing twin 3/8" fuel lines (twin electric fuel pumps.)
seems the best spot to cross from drivers side to pass side at the trans tunnel is just in front of the trans tail housing (th350). Is that approx where the factory fuel lines cross?

My car is/was a v6 EFI car. The factory fuel line runs right near the headers collector. (drivers side)

The stock fuel lines run over the top of the transmission, in the tunnel, behind the bell housing.

You can try rerouting the lines on the driver's side to get them away from the exhaust, but going over to the passenger side is just going to get you in the same situation on that side.

Just trying to get them away from the header collector (long tubes). as of now they run within 1/2" of the drives side collector and get way too hot.
creates a vapour lock issue on hot days. (WOT mechanical pump)
getting them up in the trans tunnel away from the headers is good.
I have heat insolation wrap to take care of radiant heat off the trans case etc.

Am getting the fuel system set up for the tunnel ram (future)

Well, as you please. You can lead a horse to water, but you can't make 'em drink.

Down low there is more air flow to get the heat away. Up in the tranny tunnel it's dead heat, and you're going to have to route it right by the exhaust again, anyway. Two feed lines means slower flow, more time for the fuel to pick up heat.

But, I suppose with a tunnel ram, you aren't going to be spending much time on the street, anyway.

Down low gets you right next to the headers.

Trying to go with the less evil senario.
The electric fuel pumps and these fuel lines will only be used at the track.
They will be well insulated (from trans heat and exhaust heat) in the critical areas. Keeping them away from the exhaust heat as much as possible.
Just the fact that the fuel line(s) will be pressurized is a big ++ as compared to the draw side of the mechanical fuel pump + being so close to the collector.

Once dialed in, the tunnel ram won't be a problem on the street.
This car is a week end cruiser and track racer thingie.
Thanks for your input there Five -7

i'm gonna try to get away with running two -8 braided lines along the passenger frame rail or thereabout up to the regulator on the pass. side when I get the tank back from being sumped. The way/angle my true duals are run, those lines will be more than 12" away from the exhaust pipe facing the pass side....so should be more of a PITA to route them that than worrying about them getting heat soaked.
