Are there any really big differences between models or years if you have the E4OD? Because of the hack up job the PO did on my truck I replaced the tranny oil cooler, but the lines need be done as well. Inlinetube lists 96 and 97 as being different, anybody know?

 

The diameter changed at some point to a larger size. My 95 still has the 5/16ths. I can't find a change over date, but "very late e4od" is all I'm seeing.

 

I checked out FordPartsGiant. Great resource for part numbers. They only list 5/16 as a tubing size. I just grabbed some 5/16" fuel line compression fittings, cut and shaped what was left of the cooling lines, and I'm all gravy.
