Hello I have a 2012 f250 6.7, I developed a fuel leak at the fitting on the fuel cooler on the line from dfcm. went to napa and asked for 12mm fuel line quick connects and they fit perfectly so I made my own hose with clamps and the 12 mm connectors. I know this is not ideal even on the low pressure side but it was a cheaper alternative to try from the $400 fuel line kit i would have to buy.
the new fitting works fine on the dfcm end but still leaks at the fuel cooler. I did notice a bit of corrosion on the part of the cooler the fitting slides onto, so I plugged the port and used very fine steel wool to polish it up. However this still didnt fix the issue, I'm wondering if I need a new fuel cooler.
