Installing edelbrock 1409 on 1997 Volvo 5.7L GS. Plan is to cut steel fuel feed line before last bend and install something like edelbrock kit 8135, pictured below only using stainless braided lines. Motor has existing water/fuel separater that fed previous Holley carb. Question, does anyone run second filter, above separator, such as in pic or would that be overkill and impede flow and cause starvation? Also do you think the stainless braid lines are necessary or is it a big negative on marine engine to run rubber fuel line?
