Return fuel line
I am installing a LS1 in my 62 and have to run a return line. Where would be the best place to bring it out from the tank going through the body, maybe near where the original line comes out.
Also where would be the best place to weld it into the tank so that it does not interfer with any of the parts that fit over the tank, BTW the tank is new and never had any gas in it.
I will be using an outside frame mounted electric pump.
Does anyone know if the LS1 will fit in the same place as the 327, I have side nounts welded on the frame because I have a Fatman rack and pinion frontend?
Thanks for all of your help, you guys have never let me down,

I ran my return line into the sender unit. It runs along the frame with the supply line. The LS1 should fit like a glove. I have a 6-speed so I can't comment on the trans mount.

If the side mounts are placed for a SBC you'll need some offset mounts, try some of the engine swap sites (I'm thinking of early Camaro.) Look up Chevy High Performance for engine swaps, you'll soon find what you're looking for.

I also run a external pump. I used steel braided lines and AN fittings. I ran the lines along the frame and attached them with insulated clamps. For the return line I drilled a hole in the filler neck and ran a piece of stainless tubeing to the bottom of the tank and pointed the discharge away from the fuel pickup. I did not weld in a fuel sump, I placed the pump lower than the tank and have been running this way for 4 years with no problems.
Good luck

What are using as the outlet from the tank to the pump?
On my '62 Ram Jet engine car I have an external inline pump mounted on the inside of the passenger side frame rail. I used a stock tank and tapped into the drain plug for the outlet to the pump and used the normal outlet line for the return. This works fine until you have about 3 gallons of fuel in the tank at which point any hard turn will occasionally cause momentary fuel starvation. If you do not have a sump I would strongly recommend adding one.

I don't know who your reply is directed at?, but if it's to me I will agree with you that a sump would work well with FI cars, however in my case the system I have now meets my every expectation. I used the stock fuel outlet port and mounted my pump on the frame right next to the tank I then ran #8 line to a 10 micron filter mounted on the firewall then to the fuel rail, the return line is #6 and runs along the drivers side of the frame to the filler neck. I have autocrossed and run out of fuel with this setup and I have not experienced any negatives that I'm aware of. Plus I can still run my spare tire tub (I don't) I don't know if you can if you sump your tank.

Actually my question was directed to Midnight1957. From his post I assumed he is using the original outlet pipe as a feed to his pump. On the 62 you can add a sump onto the bottom of the tank and not interfere with the spare although it will require a little fiberglass trimming.
