I ran into the same issue when installing my 040.. what I decided was to run them in parallel rather than series.. I was too worried that the 040 would just overwhelm the 255 and cause fuel pressure issues.. I opted to run a seperate line for the 040 and run dual feeds to my rail. My old setup was dual feeds into a Y fitting then single line into the stock rail. (I've got the rail still with a -6 fitting welded to it as well as the -6 adapter where the stock FPR goes if your interested)meet07 wrote:

The 040 outside of the tank is loud as s*** (mines mounted in front of the rear wheel by the frame rail)... makes your car sound like a race car.. if you don't mind its not terrible but it is very loud and it surely lets you know its working,.
