Will they work as is? Not likely. You could possibly modify them to work though. Keep in mind the carb and EFI have different connection points, and operate at different pressures (5psi vs 40psi.) Most of the hard line would probably be useable, but any flexible line probably isn't rated for EFI applications. Nothing you can't fix though.
The fuel filter will have those bastard quick connect fittings and locate on the rear subframe, similar to the SN/NE cars.
You are correct on pressures. The carb lines just have a basic rubber line, suitable for gas, that just goes over the hard line, and clamps on with a basic pressure fitting. The EFI lines have actual fuel line connects,and thicker line.
The carb line setup also doesn't have provision for the fuel filter in the rear, while the EFI stuff does. I definitely have the mount for the fuel filter still on the frame, just need a filter and the lines.
I have a line on a parts car a bit north of chicago, some rust in the body and some previous frame repair, but full interior, all the brake/fuel lines, cooling system, etc. I may end up picking that up if its still for sale in about a month so i can just swap the parts over without the hassle.
Theres also a much cheaper parts car in chicago, no interior, lots more rust on the car, but fuel lines/brakes lines intact.
One of those two cars should get me what I need, but I'll likely go with the full interior car so I can set up my 92 with interior stuff for a bit.
