fuel tank selecter switch 88 F150

possible clogged screen filter
verify pump runs do following
skide under drivers side of truck about where the drivers door is there
you should find a switching valve.....disconnect one hose at a time
coming from the fuel tanks....turn on key and note fuel flow rate

if you do have fuel comming out of both could be witching valve
if one lines has no or lower fuel flow then could be fuel pump

you may have to raise the bed to get to the fuel pump connectors

disconnect the connector and insert volt meter have someoene cycle the
key note if there is any voltage the fuel pump should try to run for a
few seconds when the key is turned on

if you do find voltaege but fuel pump not delivering fuel, replace fuel
pump....

if you have two tanks and one runs out of fuel but problem is with
switching valve...switch the hoses feeding the switching valve and you
should be fine....
