I replace them with the later bobcat fuel filter housing 6667353 for less than $60 and it comes with the filter. the advantage is it still a bobcat part number and the filter is easily cross reference to Napa, Wix or any other filter brand you wish to use.the filter system is really ok they just put it in a bad place , look at marine applications with a screw on canister filter housing. I have had good luck with the wix 33195 filter if you can find a housing for it the filter it is very common filter. I have 2 tractors and 1 backhoe and they all use this filter.
