the ones w/ the
glass bowl on the pump filtered on the outlet side of the pump - GM discovered that a better way was
the inline filter , which the factory put
on at the carb inlet - for awhile it was hard to find replacement elements that fit them properly, so most went the easy way w/ throw-away plastic filters, like most V8's got later
fire danger over the manifold? if you have leaks they can/should be fixed - no greater danger than having the carb "over the manifold", and the factory unit is less likely to leak w/ the correct fuel line fittings
