Hey, I removed my fuel tank, had it blasted and am trying to re-install it. BUT there is a blockage in the larger (of the two) fuel lines. It seems to have been there since new?The vehicle is a late '73 and to the best of my knowledge looks like it is original. How am I suppose to insert a (maybe) 3" long screen into this fuel outlet with this circular thing approximately 1/2" inside there? I am trying to get the car up and running to make to the Porsche Swap Meet next weekend.
Thanks for your help.

It may be me (in fact it probably is me), but I'm a bit confused by this question. Is the fuel line blocked, or are you saying that the fuel outlet in the tank is obstructed by something? Those are two very different things. In my mind fuel line is what connects to the fuel outlet/nipple attached to the tank, but I know terms like this are often used interchangeably. I'd like to assume you are talking about the fuel outlet since you are talking about the tank, but you then mention fuel lines. You say the tank was blasted, but is it possible you mean that you had the inside cleaned and resealed? If you had it resealed then the sealer could be obstructing the outlet if it wasn't done correctly. If that happened you'll need to clear that out. In fact, I'd go so far as to say you should probably just get a new tank as the sealer is notorious for failing and gumming everything up. I would also guess it is possible that something has fallen into or was put into the tank and is now blocking the outlet? One method for cleaning a tank is to put a bunch of washers or nuts in and then agitating the tank. One could have been left behind. You could give the tank a good shake and see if anything is rattling around in there. As far as replacing the sock/strainer, that should be fairly straight forward. You take the large nut off that is holding in the fuel nipple, remove the nipple, the sock/strainer can then be removed (if it didn't come out with the nipple), and you can then replace it. Take a good look at the diagram posted above by hndyhrr. That should make it clear.

A picture would be really helpful to clarify what you are truly asking about. And no, if there is truly a blockage in the fuel outlet it has not been there since new otherwise you would have a zero mileage car (IMG:style_emoticons/default/biggrin.gif)
