A wiser man than i offered me the thought one day that two filters were both an overkill and a cork in the bottle when it came to fuel flow. Were a body to run an in line filter that was located outside the carb, then that itty-bitty cartridge filter that carbs like the Holleys and the Rochesters came with ought to be extracted and parked.
I do agree that the location of what is apparently a plastic bodied see through fool filter does leave everything to be desired. Not sure I would want it down on the frame unless it had a metal body, or was one of those steel versions with the replaceable filter cartridge. Mine are usually the light metal bodied versions and I try to park them under the upper alternator bracket which is a quiet, relatively cool place so that the gas inside doesn't become too hot and percolate.
As for that WTF gizmo, two immediate possibilities here, One is some sort of cro-magnon era remote starter, another is a same generation security/anti-theft module, the third is some kind of auxiliary fuse block for some type of high zoot power hog sound system. The quality of the wiring looks about right; crimp on insulated spade female connectors snapped on to a row of exposed male spade tabs. One red power wire in, located on the one side, and a bunch of red power out wires located on the opposing side; probably as many fuses as there are output wires. A lot of installers way back when got paid based on volume, not on fit and finish; connections could be as raw and primitive as bare wire twisted to an existing wire and taped over. Made it easier to take the product out again when it went POOF! I get the time is money schtick; that was the mantra of a lot of the "shops" that sprung up, made a few bucks, and closed down again, only to re-open under a different name a month later and two blocks over.
What got my attention as well were those loud red colored plug wires with no looms or stanchions to keep them off the manifolds and that plastic sphere down and sort of behind that chunk of aluminum A/C plumbing. Think that is a vacuum canister for the cruise control?
