Stock Fuel Pump Question
How large of an injector can the stock pump handle? I am looking into some things and I think I will need either some 30# or some 37# at the most. I will be staying N/A for sure. Thanks for any help!

The stock pump can "handle" the injectors you will just run out of fuel before the injectors give up. Stock pump can make about 400-430rwhp and so can the stock injectors. Rec. to upgrade both anywhere over 400rwhp.

Thanks for the info Nate! I really don't want to have to change out my fuel pump if I don't have to. I swapped out the pump in my wife's 2000 and that wasn't that difficult, just not sure how it would be with the '98. I'll change the pump though if that's what it takes.

The stock F-body fuel pump doesn't "handle" the stock injectors very well. At WOT, pressure drops significantly as fuel flow increases. This complicates tuning because it undermines the injector calibration tables..
