Fuel pressure and flow numbers for 1990

Couldn't find what I needed. Does anyone have the fuel pressure and flow from the stock, in-tank pump for a 1990 FB with 305 TBI Auto?

Thanks
Matt

A 195 lph pump will work. The TB will regulate it down to what it needs. Then you have enough pump already installed if you want to go TPI later down the road....

I don't know anything specific...but....

Most TBI units run around 15-25 psi.
I suggest that you use a bypass regulator and adjust it down to 5 or 6 psi.
