I went through this about a year ago on my 7, I had a dickens of a time because someone had installed the wrong fuel filters and there are some that look right but are not. I finally got it figured out and the numbers are current, the originals were the sock type and have been updated. I have to do a bit of research but I will get the fuel filter numbers for you. Tad

Check out my HD7

Wix oil and fuel filters, drop the first digit from the Wix to get the Napa number,

Oil -51005
Primary Fuel -33061
Secondary Fuel ser#17478 up -33511
Secondary Fuel ser#17478 -33043

If I recall correctly there are gaskets (quad seals) for the filter to base along with gaskets for the cup (they should be included with the filter) and there should be a spring and washer assembly to retain the filter inside the housing on the secondary filter, be very careful on the primary, there is one almost exactly the same but a bit longer by about .250, it will crush the filter when installed. Hope this helps Tad

Hi! Thanks for all the info! I just got the replacement hydraulic pump installed and serviced the transmission and final drives, so now all she needs is an oil and filter change so I can take her to this years military show in western Idaho!!Here's a link:: http://p8.hostingprod.com/@imvpa.idahomotorpool.com/pictures/flyer10mvpa.jpg

When you are all said and done I am sure we would all like to see pictures of the event. Does you 7 have the Baker blade or the Garwood? Thanks Tad
