What is the most simple way to run two FD stock pumps? and would this supply higher flow, pressure and reliability over one Walbro GSS#341, 255lph HP pump. All comments are welcome..

 

stick with dual nippon denso pumps, I have heard that walbros fail more often then the nippons...I have dual 280 lph nippon denso's. Some people run two fuel feed lines to each rail, some y them together and run one line to feed both...some run 2 relays for each pump, some run one large current relay, some run a single power source to a distribution block and then two fused power sources to the pumps...its all in preference. I run a single 70 amp relay to power both pumps, that way if the relay fails, car will just die, vs if one relay fails you would loose pressure and might not catch it till its too late...if one pump goes, then you would pull mega current through the wires and potentially melt wires...but regardless, if a pump goes, you will loose pressure and would have to catch it on the wideband or fpg or rig up something that warns you when it drops and doesnt hold steady with boost.

 

Thanks Much..
