replaced fuel transfer pump put rubber line into fuel can truck ran fine when i tied into fuel tanks truck stalled there are no cracks in line coming from transfer block valve on the frame so i am wondering if that valve is bad ? priced one from ford kind of expensive. does anyone make one aftermarket? and i may just by pass valve by cutting lines and if that does not work i have to drop tanks anyway any advice
