![]() I would say that is not an utter emergency, but when the funds allow it, get a bigger pump. I an not big on carb info but it seems that it would be better to matain the pressure throughout the 1/4.

![]() I have to agree. If your pressure is dropping while stompin on the gas then you need a higher volume pump.
Just make sure that you don't lean the motor out too much, or else you're gonna need more then a new fuel pump ![]()
