For 1991 Chevy C1500 - 305 - 5.0L - Fuel injected

I'm running a little rough at stop lights with the intermittent chugs and have loss of power when accelerating. Once in a while I smell a little fresh gas while accelerating and there's a bit of gas on the bottom of my air filter lid. Fuel injection is out of my league and I'm hoping it's not the pump.

I'm about to go check the fuel lines to make sure everything's tight but haven't noticed any leaks anywhere.

Is there a way of narrowing down what the issue could be or is it generally start from front to back? Any input helps big time

Thanks.
