Case 1835C Fuel Filter Mount Question

Thanks in advance for any help. I have a 1986 Case 1835C with the Continental diesel engine. Does anyone have a photo or drawing of the base that the rectangular fuel filter mounts to? I am trying to see if there are 3 tubes protruding out that the filter slides up on. My base only has 1 tube at the top. The filter has 3 holes with O-rings. 1 at top and 2 at bottom of filter.

Thanks again,
JW
