Small Block vs Big Block fuel line

[Jim V.]

Here is pic of small block fuel supply line to pump. Note 45 degree angle and position. Can somebody post a big block photo showing the 90 degree supply for comparison. Thanks

Jim -- the more definitive parameter is the length of the fuel line (ie. from the center of that clamp (which is in the centerline of the bolt of the idler arm) to the sealer bead under the rubber hose. I would say (without laying a tape or wire along the tubing) that the BB fuel line is about 4" longer from the clamp to the bead. Angles are subject to Bubba bending over the years.
