Randomly sputtering dieing and fuel filter dry

[p4587]

I recently had my tank out and of my 69 bug and snapped the end off a t fitting in the ventilation system. The now broken t fitting connects a line from the front corner of the tank(front of car) back to the filler neck. I assume the line is vent fumes back to the neck. I was in the process of moving and just left the line disconnected.

I have recently started driving the bug again and 3 different times the car is running fine and will start to sputter and cut off at speed. After a few mins I notice the fuel filter filling back up and she starts up and goes again.

Now my questions

Does the fuel ventilation system have to be a closed system?
If not I'm guessing I either have crap in my tank or fuel line.

Or could the be a fuel pump issue?

I just replaced the floors on the car and didn't drive it much before so I don't know if this a new issue or not.

The vent system on earlier bugs was simply a hose from the fuel neck to the underneath of the car. Leaving the port open on the tank itself will only allow gas to splash in the trunk and give you gas fumes. Wont impact the car running.

One way to see if the tank or main line is clogged it to clamp the soft hose above the rear axle, remove it for the line to the engine and then take off the clamp. If you have a good flow, then your problem is elsewhere.

My first though is needle valve stuck closed in the float chamber.

What I had to do in the past; Suck on the hose ahead of the fuel pump. If you get a mouth full of gas then suck on the hose between the fuel pump and carb. IF you get another mouthful of gas then the problem is in the carb. OR...if the problem was vapor lock the car may have cooled by the time you rinse out the gas from your mouth.

When you had the tank out did you change the sock filter that fits inside the tank?

I just cleaned out the tank in my '69. PO had removed the sock filter (or it disintegrated.) This is bad news because any little thing can clog the outlet. When the sock filter is installed the surface area increases dramatically and it is impossible for a small bit of debris to stop the flow.

BTW I bought a new EMPI fuel outlet kit and the sock filter that was included was pathetic. I threw that part away and replaced with a proper german one from WW.

That might be the problem. Are you referring to one of these http://www2.cip1.com/ProductDetails.asp?ProductCode=VWC-111-209-147-AP

If so mine doesn't have one. I have read about the screen in the tanks but assumed they were in earlier models.

How do you install one of these, really long needle nose pliers?
