Ok guys and gals, I hope I can ask questions here so here it goes, I swapped a v6 out for a different one but I can’t for the life of me figure out how to get the fuel to stop non stop running other than the fuse, I’ve changed a black box (I can’t think of the name of it) on the rail and the fuel line style regulator and still nothing, it is a 99 so it has the return less style fuel system, so I’m stuck, could it be a problem in the tank, i would greatly appreciate any input, thank you in...

V6 swap not going well
