I bought a 2001 and its got the 150 series and i was wondering if you can run stock injectors with it, if not I will end up checking the size that is in it. just didn't know if you don't wanna tare into the motor to find stock injectors in it

 

If you have the fass 150 yea it doesn't matter if you have stock injectors. But if you have 150 injectors ya you will want to get a fuel system

 

It almost seems your looking at the fuel system backwards. More lift pump pressure/flow doesn't mean you need to deliver more fuel into the engine. In reality, when your looking to deliver more fuel, you need a higher flow rate from your transfer pump. If someone installed a FASS150 on a stock truck, they either had plans to upgrade, or it was more cost efficient then a factory replacement. That FASS150 will fuel the engine beyond the fueling capabilities of a VP44.

 

Ok never really understood I just figured it might have bigger injectors my truck smokes I mean won't black out a four lane highway with no programmer or is that just the the nature of the truck?
