Home DIY gasoline station

What else in terms of safety or functionality do I need to account for in
designing this Amazon-sourced small-scale home DIY gasoline station?

I had been refueling at home for five decades, usually using a simple
lung-activated siphon action with a 1/2-inch ID 10-foot-long vinyl hose.

For the past year, I've been refueling with this portable gasoline pump.
 <https://amazon.com/dp/B0DLDKHL7B/>
But that portable gas pump is slow & it does not shut off automatically.

I want to design a faster auto-shutoff home refueling system to go from a
standard 5-gallon Sceptre portable gasoline container to the automobile
gas tank outdoors (with plenty of ventilation & no flame sources nearby).

I am aware of the dangers of static electricity which is the major concern.
I am aware a metal can would be better grounded than the HDPE gasoline can.
I am aware that slower flow rates are safer in terms of static buildup.
The 2GPM flow rate of the gasoline pump is a major component in the system.
I am aware gas cans must NEVER be placed on an insulated surface.
I am aware that very low humidity is conducive to static charge buildup.
The fueling process will never be left unattended.
I am aware of the dangers inherent in storing 5-gallon gas containers.

There will be no vapor recovery which isn't required for 5-gallon systems.
Spill containment isn't required but a shallow metal pan is available.
A Class B fire extinguisher is mounted near the fuel storage area.
I have personal protection equipment (gloves, goggles, welding apron).
Gray fuel-spill pads were obtained previously from the Costco gas station.

All parts below are expressly advertised as designed for *gasoline* fuels.
All equipment will be essentially on the ground (i.e., nothing elevated).
However, 20 feet of stranded copper wire, 12-14 gauge is available.
The hose will be aimed close to the bottom of the gas can to minimize.
potential splashing and therefore accidental static generation.
The 12VDC gasoline pump is attached to a 12VDC battery via clamps.
If desired, a ground for the vehicle to a copper stake can be added.
If desired, a stainless-steel nut will be used as the hose weight.

If I order the following parts, do you think I'll have any major issues?

 5-gallon HDPE scepter gas can https://amazon.com/dp/B0BRT72MKT/>
 3/4-inch NPT Automatic Fuel Nozzle <https://amazon.com/dp/B0DZCM1HYH/>
 3/4-inch 360-degree fuel hose swivel <https://amazon.com/dp/B0F26DTBVC/>
 1-inch gas flow meter w 3/4" adapter <https://amazon.com/dp/B0F334N1JR/>
 12VDC 2GPM gasoline pump w clamps <https://amazon.com/dp/B0DFCRH64R/>
 10-feet 3/4-inch black gasoline hose <https://amazon.com/dp/B0DCG951RV/>

The initial order of operations (pending improvements) is:
a. Connect a grounding wire from the pump to a ground on the vehicle
b. Place full HDPE gas can on the ground & remove gasoline bung cap
c. Insert the nozzle before starting the pump (to equalize static charge)
d. Drop open gasoline hose (perhaps weighted) deeply into the gas can
e. Press the gasoline pump on switch & determine proper gasoline flow
f. Maintain nozzle continuous contact with the filler neck throughout
g. Allow the nozzle to automatically shut off the flow when full
h. Wait a few seconds for nozzle drips & static charge to dissipate
i. Shut off the fuel pump on/off switch shortly thereafter
j. Put everything away but always disconnect grounding wires last
