Re: Do I need a fuel pressure regulator?

[Jimmy Peavy <peaver63@xxxxxxxxx>]

If the floats handle the pressure, and it isn't spewing gas out
somewhere, what does it matter?
I've run similar pressures on the same carb for 35 yrs now. And I did
read the instructions advising me of the recommended pressure output.
Car has always tolerated the pressure , and most importantly, the
floats have as well.
If it's doing well, why change?
New floats are probably less than the regulator.
