just finished hooking up my OTTP return style fuel system. just outta curiosity what should my fuel pressure be? thanks in advance CSS

 

no one?

 

58 psi i believe

 

You can make it whatever you want it to be, but stock is 58psi Im running a 42 base now with 1000s though.. Oh yea, check this with no vac line hooked up to the regulator

 

this

 

thanks guys. i really appreciate it.

 

Like they said 42 is good. I would think however that 43.5psi is perfect...

80's flow 80lb/hr at 43.5psi. So if your base is 43.5psi, you can use 2 as the voltage multiplier and 40 as the injector flow in HPT...

That gives you a nice 37ish psi idle, and shoots your pressure more than high enough for top end fueling for a moderate pulley E85 TVS.

Anyone want to explain why 42 is the sweet spot instead?
