Im going to try this or try a pump out side the tank. Anyone know if the nnbs trucks are returnless or not?

Returnless. So no in-line pumps.

Refer to post #20.

I would like to see how others have done it though.

Cut out the fuel filter and put the 2nd pump in its place. Then a y-block for the 2 pumps into one line.


Lol yeah that worked. The latest one I did used a filter outside the tank. Had to use a new line so it wasn't a big deal. Its more serviceable that way anyway.

That fuel system is actually in my old ECSB...so if you see a blue 08 silverado with SS wheels, it might have a 1000hp fuel setup already in it
