My Nova is basically all Aeromotive! And it has performed flawlessly!
I was very concerned by a video covering the installation of the "Aeromotive" fuel tank module as the venting of the tank was capped & sealed. Only later in comment did he claim a roll over valve was employed on one of the tanks fittings. Please consider a video to cover this issue as fumes can fill a garage overnight, why a roll over valve is needed, keeping tanks from collapsing, or gas station pumps kicking off during refueling. I like many, installing a Tahoe LS in a 50 year old truck but asked the programmer to allow purge as I installed an activated carbon canister to store & burn the fuel vapors I paid for. Problem during refueling come from no tank venting as new gas tank caps increase vent pressure from 1 PSI to 2 PSI. The hydrocarbon rich atmosphere trapped in the tank has to go somewhere. We know it depends on how the vehicle is used for, designed use and vented to allow air in via a carbon canister while having an active roll over valve that closes as soon as liquid fuel touches it. This causes the gas stations pump to react thru the aspiration tube to shut off. Thanks!

100 MICRON befofe pump means feed to the engine?
I am confused slightly on your concern but placing a 100 micron filter before the pump is the first protection for the pump. Pumps may wear as the may provide venting for normal caveated fuel in stage one of a vane rotor creates a vacuum. This feeds stage two vane rotor to push fuel through the pump, pass the spring loaded check valve into the second filter to the injection rail.
Most all vehicles use a bucket, Venturi pump to keep it full providing the pump with un-aerated fuel to create volume. Without volume, you cannot generate pressure. For example; look at a boat propeller in the water. As it spins, it creates a vacuum on the leading edge of the blades. This generates bubbles reducing volume. Water can boil at room temperature in a given vacuum. The higher the vacuum, the more boiling occurs. Air cannot be compressed leading to a drop in pressure, while liquids can be compressed producing pressure. This is why pumps are placed inside the tank as this leads to vapor lock. In 1976 the Datsun 280Z & Cadillac Seville used electric fuel injectors. A helper pump inside the tank kept fuel of sufficient volume to a frame mounted fuel pump to eliminate vapor lock. I enjoy EFI and its attributes as the days of vapor lock are gone. But the parts inside the tank is more complex as a bucket is used, return fuel is dumped back into the bucket and most use a tiny amount of high pressure fuel to pass thru a Venturi at the buckets bottom. This fills it regardless of the tanks fuel level. But this requires a larger hole in the tank. Plus hanging a fuel level sending unit on the side and perhaps a thermistor that changes resistance once levels drop shown on the dash as a low fuel LED. Level and low fuel maybe displayed as 10 second samples to update the dash indicators. So turning a big loop onto or off an interstate does not turn on the low fuel lamp or starves the injectors causing a misfire. Misfire counters numbers were relaxed in 1997 after the service engine soon lamp came on. This leads to customer dissatisfaction and unnecessary dealer visits. Unfortunately the cost of tank technology is high as even venting via the cap was increased from 1 PSI to 2 PSI so hydrocarbons did not vent. Have you noticed changes to you portable fuel tank for your lawn equipment? Once again, low level smog as hydrocarbons and sunlight met at 10,000 feet. Even Indian encounters by Lewis & Clarke in current Oregon Were told that the area to the south was haunted by their grandfathers, grandfather by smoke from campfires and not considered to be used by Indians! They were describing Los Angeles because of its bowl like topography that held smoke from Spanish explorers. It's in the records from 200 years ago.
