I replaced my FSV in 2002, and I actually used one that was meant for a plastic-line system. The rubber hoses BARELY fit on the nipples (wrestling them on while getting bathed in diesel fuel was NOT funwouldn't want to be you when your FSV takes a ****......
if the plastic line FSV already costs $150.....your rubber hose FSV has got to be positively ungodly on the pricing.
), and between the tight fit and the hose clamps, they've been holding strong for the last 8 years 
no leaks whatsoever...
