i have a 63 t-bird and have a problem with fuel when driveing over 65mph.the car acts like it is starving for gas. had the 4bl carb rebuilt and all lines checked,especially the metal to ruber connections.
i have a filter at the carb and one external filter between the pump and gas tank ( they were there when i bought the car.) mechanic said the filters look clean.
question; should the filter be between the pump and tank or between the pump and engine and dose it matter if there is another filter at the carb.

when driveing over 65mph for a mater of time the engine starts to flutter and i have to pump the gas pedal,which dose nothing, but the engine seems to hit an idle and never stalls out. i pull off the road and wait a while(the engine stays at idle) and then accelerate out - it's fine for a while then in time dose it again only when cruising at/over 65mph.
sure can use some help.
thanks as always, AL

Check to see what volume the pump is putting to the carburetor. It should be around 1 qt in 30 sec. If not, you have a flow problem, pump filter or restriction.

Does not matter where the filter goes. I used to put on two. One after the pump to
protect the carb and one before the pump to protect the pump. You need to do a volume check, pressure test, and vacuum test. You have one of two problems. Maybe
both. A rusted out gas tank plugging the intank filter or a plugged vent in the gas cap.
Or the wrong gas cap. You don't say what engine or carb. If the filters are water logged
they will look clean but plugged solid. What pump is on the engine as in what make ?
