Question about 1989 Volvo 740
When the fuel gets below 1/2 tank the car starts to cut out during excelaration . I'm guessing there could be a crack in the fuel line that goes into the gas tank and once the fuel gets below a point it starts to **** air.. Any other ideas?? I don't think its a fuel pump issue, because its had this problem for years..
Fuel pump and furel gauage are seperate cicuits thoug possibly on thr dame unit. The full gauge may be out of calibration And nothing more. If the car runs out of fuel at half tsnk confirm and the fuel pick up is defective both units wikk come out togeter anyway. good luck

You have an bad intank fuel pump,or prepump.Will good if pass an 1/4 to 1/2 tank no problems,because its running off the main pump,it needs the prepump to help push the fuel out,Listening by the rear gas tank,do you hear a hum?How does it sound,up and down,this is your prepump.
