I have a '99 B4000 4.0L with 107k and have been attempting to replace the fuel filter. I have three versions of the quick-connect tools and can get one side of the filter off but the other side simply will not come off. I think my only hope is to cut the short section of nylon fuel line and repair it with a new quick connect fitting or clamp to the filter. Anyone have any idea where you can find replacement quick connect fittings or repair kits. A couple web sites show them (Ken-Co and their Canadian subsidiary) but no retailers listed. I am afraid I have weakened the nylon hose bending and tugging anyway as it is a bit frayed so I need to replace anyway it looks like.

 

I have not done this but let us know how it turns out.
