AFAIK, most never fuel injection systems use much higher fuel pressures in their FI. I'd imagine this is to achieve better fuel atomization for fuel economy. Since I have tunable FI I was pondering what it would take to increase the runing fuel pressure and wether it would be worth it.
OBVIOUSLY the fuel supply/return lines should be upgraded to steel for safety. Would new injectors be necessary? The FP regulator would need to be replaced. What else? |

Upgrade the injectors. Going more than a handful of PSI on the fuel pressure appears to have a pretty negative effect on their lifespan.
