I am getting ready to button up my fuel system after pulling the tank for cleaning and replacing the soft lines.
I have a 72 that a PO carb converted. The return line is capped off back in the engine bay past the plastic fuel line, which seems a bit foolish to plug the line so far back. Does anyone have a solution for capping the line at the tank? I do evenaually want to change back to FI so I don't want a solution that is permanant. |

just cap it at the tank it is absolutely stupid to think of any need for recirculating fuel in a carb system with a pressure regulated pump (as are 99.9% of all carb-car fuel puump systems) - just install a simple psi regulator at 2-3 psi before the carbs, , and the simple fuel pump (like a Facet) will just stop sending more fuel - no need to run it back to the tank - that's just dumb! caveat - - some oem early german 911/914-6 fuel pumps DID have a provision for pressure relief via a 3rd pipe - but a Facet does not require this - go buy a facet pump .

They are used on millions of factory designed current vehicles even on carbs it is still better than non circulatulatory systems it is better only a little better but still better not accurate to call a superior design stupid or dumb... brant |
