My son and I are working on his 79 TA (it's a painted shell being reassembled) and need to install fuel lines (and brake lines as well) prior to installing the rear suspension (Ridetech 4 link). We'd like to use factory lines and clips for a neat install, but wondering if we'll run into problems with the factory layout and line sizes (originally a 403 car).

The feed line (3/8) and brake line are on the LH side, and the return (1/4) and vent line (5/16) are on the RH side. My thought is we could jettison the factory return line and use the larger vent line as a return. But will 3/8 feed and 5/16 return be enough? Car will be LS powered (408), Terminator X, about 500hp or so. Also wondering whether having the feed line on the LH side and return on the RH side will create difficulties when it comes time to tying into the fuel rails?

Haven't decided on a fuel system yet, so may not need a return, but it would nice to have it in case I end up there. On my Formula I went with a Rick's tank, ZLI fuel module, Vaporworx controller (and bent my own lines), but looking for something less expensive for this car if possible. Suggestions would be very welcome.
