FUEL STARVATION?
 

my friend as a st170 and when it gets below 1/4 of a tank on fuel it seems to sufer from fuel stavation, as he is coming out of some corners/roundabouts


will change the fuel filter for him this weekend to eliminate that but i wanted to know is this a common problem and is there anything that can be done to the fuel pick up in the tank if it is this?
or is it just a case of tell him not to let it drop below 1/4 a tank??!!
