so looking for a fass 150gph plus one extra little thing... the fass kit is nice but the one thing i liked about the airdog 2 was that it came with a fitting that tied into the return line at the fuel cooler so you don't have to cut the fuel neck.

so im looking for that additional fitting as well.

 

Hi,

Are you looking for DFD-4000 for the duramax. If you still need parts drop me a line. I help the moderators with discounts or free parts.

nope, it ties into the return line at the fuel cooler for the return line coming off of the fass pump. i ordered it from summit.
