That is not going to work if you are wanting to go with 60# injectors. Pm mIghtey mouse and ask him your self how high his Fuel Pressure was...... Ill just tell you......... 80PSI 60 psi base (so the 43 psi base wont work) and then 20 psi of boost thru his rate rise reg took FP up to 80psi of FP and he believes and so does alot of other people that he is taxing his fuel pumps to much.........

I went to this setup because I had problems in the past with intank setups. It was frustrating because it's a pain in the bum to change the intank on our cars.

I agree with you John it is a pain in the @$$ to change the pump in th etank and i DID NOT wan tot cut a hole in the hatch...
PSJ, Did you run dual -8an feeds to the front???
Im wanting to do it like what Brian did....but withe both -8an feeds coming out of my sump and into a Y-Block and back into a -8 to help keep FP up.
Then split it again to each rail up front.
John are you running dual relays also?? One for each Pump???
