No, not true *IF* you select the right pump. Once again, SU's want to see 2-3
PSI. There are many pressure ranges of pumps available- the common American
Carb type being 4-7 PSI. A regulator can bring it back down to the right
pressure, but they cost as much as the right pump to begin with.
Can gross jets help this problem? No. In fact, in my experience, needle
valves will seal to a higher pressure than Gross Jets.
Bottom Line- Buy the right pump.
