Drilling out the banjo bolts poorly resembles help if you have a fueling module and bigger injectors. You still have tiny holes and the fuel still has to make a 90 degree turns in every joint.
The proper way is to get some big straight thru fittings and lines...I got mine from www.vulcanperformance.com
I think Russell products has fittings that'll work too.
Have you put a lift pump pressure gauge on yours yet?
