For a 5 litre v8 producing (hopefully) 350+ bhp? Fuel pump is a Bosch 044.
I am looking at either -6AN or -8AN from Speedflow. Or even -8AN feed and -6AN return. The price is no different.
I use -6 feed and -6 return, but many use -8 feed and -6 return for 350bhp, i'd be going the -8 feed route.
-8 it is then.
