Low Level Fuel Problems

[YT068]

In my VP when i get down to about 1/3 to 1/4 of a tank the car starts to splutter and carry on. Would this be sludge and crap in the tank or would it be some type of pick up problem? not too keen on taking the tank out to find out its some other problem. can anyone help out there?fue

most likely broken return line inside the tank to the swirl pot or the swirl pot itself is cracked or shifted off the bottom of the tank theres plenty of threads on here about it and how to fix it it happens a lot
