(quoted from post at 16:04:38 01/17/20) First where are you located, general area? People maybe able to give you better ideas on finding parts with that info.
Do you know where you nearest Case construction equipment dealer is located or is that what you want to know?
Do you have a parts manual? If not do you know about and use the on line parts books? Having part numbers helps with searches.
Is this picture your fuel filter set up and are you looking for item key number 20? If not post a picture of what you have.
Located near Port Jervis NY, 12771. I do not have a parts catalog but I went to case construction website and the parts I tried to order are no longer available. I don't have a phone number for a dealer either. The tractor places within 30 miles of me were not helpful either. I did get the 3/8 fuel line, replaced most of it but noticed I did not have a bleeder for the secondary fuel filter but I temporarily found a 10mm x24 /3/4 " bolt to plug the bleeder hole for no..thanks Jerry
