My truck has been modified with a big line kit, relocated the fuel pump to the frame rail. It has 1/2" lines into and out of the holley blue fuel pump on the frame. Trying to upgrade my fuel system, I recently ordered a FASS DDRP pump, and discovered it is designed for 3/8" lines.

What modifications need to be made to use this pump with my current setup, or what modifications do I need to make to make it work? Thanks.

 

I'm not positive, but I believe you could use a JIC fitting and adapter from 3/8 to 1/2. Try giving vulcan performance a call and I'm sure they will have the fittings to hook you up or atleast be able to guide you where to get em. That'll let ya use the push lock fittings if you wanted to as well.
