I need to replace the Fuel Line from the Fuel Pump to the carb... a PO routed it OVER the valve cover. I have Vapor Lock problems ALL THE TIME. Also going to replace the Metal can filter with a plastic one.

Question: When I remove the fuel line from the exit of the Fuel Pump, will the gas drain from the tank? I am assuming not...

Thanks, Mark

You will have some seepage as it is below tank level. Just put a short piece of hose on the nipple with a shorty screw driver stuck in the end to block it while you're forming the new fuel line to the carb. Get a length of 1/4" split plastic wire loom to put around the metal fuel line so it doesn't absorb as much underhood heat. This will stop the vapor lock problem.

Just gushing out

When I removed the line from the Fuel Pump outlet, gas just gushed out, like no tomorrow. Would this indicate a problem in my Fuel Pump? It is the stock mechanical one. I was assuming from the prior post that minimal gas would flow from the outlet.

Please advise.... thnx.... Mark

The fuel pump is lower than the gas tank, so it WILL just flow and flow and flow...
I think Otto was suggesting that as soon as you remove the line, have a piece of rubber hose with one end plugged ready to slip over the pump outlet nozzle. Or, just take a pair of vice grips and GENTLY squeeze the rubber line at the pump inlet flat, and that will block the flow as well.

OK. Well, since I had to replace the entire line from the pump outlet all the way to the carb, I guess what happened was supposed to. I got a length of line on pretty quick that had a plug already fixed in it, but there sure was a lot of gas spilled during that time.

Well with that and a Pertronix installed today, not a bad day.

Thanks, Mark
