May sure you do them one at a time. get one crossed and it won't run. ""No short cuts"". Get proper diameter fuel hose most hardware stores have them. Remove hose measure cut leaving a 1/4" for the slack (easier to cut some off than cut too short).

The filter is in the tank. disconnect at the carb or primer bulb ( can' remember where that one connects) fish the filter out the fuel cap opening. pull the hose from the tank. measure and cut. (if the right size fuel hose is used the fuel hose seals around the bottom of the gas tank) push the new fuel hose up from the bottom of the tank and out the gas cap fill hole atach a """ NEW """ filter and pull the hose down and connect to the bulb or carb. Look inside the tank and see if the filter is in the same location as before you pulled it out.
