Target hp is 500. Is it necessary to upgrade the fuel filter to a high flow filter?? I was planning on getting the aem factory look filter. The upgrade I have for my fuel is a 255walbro in tank, 1000cc RC, STR fuel rail, upgrade 6an line from fuel filter to fuel rail and fuel pressure shown 50psi. If it is not necessary I will just leave the fuel filter how it is. Thanks

 

540 with a walbro, stock lines to the stock filter, -6 lines to the rail. basically like your setup. i think you will be fine.

 

you can make 630-650ish on stock lines and filter.. you will be fine
