Hope this doesn`t give you fuel filter envy.My POS truck I use for work has Two filters one for each tank before the switching valve,one after the valve,one after the pump,one in the carb.Why?.Because my 77c10 is a theft recovery,that got recovered out of a river bed.I`ve pulled all the hoses,tanks twice and still can`t get all the Crap out.Used to plug the filter weekly.I changed them all six months ago.Oh well what do you expect for a $150 work truck.LOL.Jon /forums/images/graemlins/grin.gif
