I have a 1980 K10. mostly restored...Doing the lq4 swap.. It has two new fuel tanks and new selector valve for them... I have an inline walbro 255lph. will this be able to get enough fuel if i connect it on the engine side of the valve? or will i have to run 2 in tank pumps? i know the second option is better.. however.. will the selector valve handle the added pressures of EFI fuel pumps?

thanks
