You might have to pull them to get numbers off to cross them. terry Quote Link to comment https://www.bigmacktrucks.com/topic/53639-filter-numbers-1963-b-61/#findComment-401100 Share on other sites More sharing options...
j hancock Posted June 23, 2018 Share Posted June 23, 2018 The fuel should be Wix 33090. The Luber Finer style takes oil filter 1554 and the oil clarifier style takes a 51233 oil filter and a 15114 gasket. Quote JimIt doesn't cost anything to pay attention.
