Do you absolutly have to upgrade your fuel pump right away when you switch to #24 injectors? This is on a 90'

 

No. You can run the stock pump with 24s. My bro in laws car has stock pump and 24s, intake, cam, t-body, mass air, full exhaust +more runs 13.7s. If you start to use nitrous or supercharger you 100% need to upgrade. If you are looking to get a new pump then dont buy a stock one, upgrade to a bigger one.

 

yea i have a 190lph pump, but i dont have enough time to put it in rright now. ok but i am glad to hear that. also how big is the stock pump

 

I think the stock pump is like 85-95lph.
