Took the fuel pump assembly apart to figure out why I get poor fuel delivery at close to a 1/4 tank of fuel. I also wanted to see how the pump was modified for the return. They put the output out the top in the middle and submerged the in tank pressure sensor. I can't get the Kpro to fire on my computer, but is that something that is normally shutoff so submerging makes no difference? This is an E85 setup, and has a short, but really fat on one end unmarked fuel pump. The strainer also had a hole and the guage sensor had corroded at the terminal, so I fixed that as well.
