I'm about to get a blower and was wondering about fuel pump setups, I have a 155lph in tank pump now, thinking of going to a 255lph Walbro in tank, or could I use my 155lph in tank and a 255lph Walbro inline would this even work,or get a 255 in tank and a 255 inline, using 42# injectors and looking around 400-450 hp, any ideas.

I BELIEVE that an in tank 255 would be good for your setup. Someone with more knowledge in the matter should chime in though.

A single 255lph intank is supposed to safely take you well above 450rwhp... Adding a t-rex inline would never hurt... Any more power than that, and the lines themselves become the bottleneck
