need to know what the stock fuel volume is on a 99GSR not the fuel pressure but the volume. i put a 99GSR motor in a 99 Civic hatch.but i think i need to change the fuel pump.

 

Yes, you should change the pump for best results. FP is between 48-54psi

 

now way! stock is btwn 38-42 with the hose on. HTH, -C

 

So far all the hatchs I have seen do not have a fuel pump that can supply the B series VTEC engine with enough fuel.
I am not sure of the flow rating. I do know with the B18C1 and the hose disconnected, it runs stock at about 50 PSI.
The last hatch I saw on a dyno had a B20VTEC and the stock CX pump was failing at about 42 PSI.
