Really bad idea to drill the stockers, they are just pot metal and many break on install. Best idea is leave it stock or use an aftermarket that has been specifically machined from different material and ported for least turbulent flow.

 

Huh, I stand corrected, now I'm gunna have to go look at one of the spare motors.

Why not just remove them and use an NTP to ORB fitting in the front of the motor and reverse the fuel flow. I don't see why you would need the high flows after the injectors.

 

They advertise the stock banjo bolts as " The last points of restriction in our fuel systems". From the small amount of info I could find on these, it just seems like a way to make money for them. Unless u plug one or your making 500hp plus and running a quadzilla hpop. It's just super overkill.

 

Only reason I can dream up is so that your FPR doesn't see a lower pressure than the injectors (and other upstream components) due to the restriction of the banjo bolt.

 

high flow pump at idle could create to much pressure before the outlet banjo and thus not let the regulator control fuel pressure at idle.

 

I've now done it on 6 engines and not one failure. Like I said though unless you are making butt tons of power you won't notice any difference.
