I have twin
Lehman 120's and am looking to replace my
fuel lines (30 yr old copper). The original lines are 1/4 inch throughout from the tank to the racors (900's) and from the Racors to the
lift pump. My Westmarine guy seems to think that is too small. Is 1/4 adequate or should I go slightly larger when I replace the liness. Also, what micron replacement
Racor filters do people recommend for my setup.
