Ok I got the instructions and understand the install but I'm a little confused when it comes to the returns on the factory fuel canister. since the canister comes out what happens with the banjo and hard lines on it? the feed isn't doing anything already as I have a Fass pump but the returns are still operating as normal and then there is a return coming from the Fass to the filler neck I understand that the cp3 and prv return go in the fuel block then out the back as one but what about the return on the back of the head? Any help is appreciated
