Next before i bought the car the previous owner said he had to drop tank for something, so now fuel gauge only goes from 1/2 to Full,it will only take 5 to 6 gallons at a time and when it get down to 3 it stalls out when i stop or turn to fast. What could be problem may be i can fix before i decide to drop the tank.

any help would be appreciated. pix coming sood

 

Problem #2 sounds like a fuel pickup issue.

 

that is located under the rear seat right

 

Yeah, but on the ef's you gotta drop the tank to check it out. Sometimes the strainer sock falls off in the tank, causing fuel pickup issues. If the stock sock is still attached, it sounds like the pump is going out. Maybe you could find out why the previous owner had to drop the tank?
Good Luck.
