3.0 6-cylinder engine. What size fuel lines do you run from the fuel pressure regulator to each carb? I am running PMO carbs with PMO fuel pressure regulator. 9mm or smaller?

(IMG:style_emoticons/default/smile.gif) I used 5/16" fuel line and it fit the stock nipples on the Weber carb's perfectly. Use correct size FI hose clamps, never use worm gear clamps. Be absolutely sure the fuel line meets current SAE spec. This fuel line is ethanol safe, but even with the correct line it's best if you can use pure gas. http://www.gates.com/oreilly/tech_tips/Ins...uelLineHose.pdf With the PMO regulator you can use an FI pump, but be sure to use FI fuel line between the pump and regulator if you do. |

Thanks Mark. I actually purchased the carbs used so I dont have any documentation. I guess I could call/email PMO |
