When you replaced the hoses, did you clean out the vent itself?...if so, sounds like you've done all you can...next step is to cut thru the sealant around tank-cover and remove sender unit...not as painful as it sounds and it'll help a LOT in finding and removing the gremlins from your fuel system... ;)...removing the tank-cover assumes there is no round access cap already in place... ;)...
