Dauntless Drivetrain Change

When I originally acquired Wilson 30+ years ago,  it had a Buick V6 from a '65 Olds,  (as I understand it).  Those only had the one line.   In 2018 I replaced that engine with a Dauntless from '68 Commando.  It had the 2 line "return" fuel pump,  but I was in a time crunch then,  and was not sure of best practice on how to dump the returned fuel into tank,  so I put the 1 line mechanical pump back on.

The 2 line should certainly be better to help keep the fuel cooler.   

I was planning to try that next,  but decided instead to replace it all.   

Cool!  . .  good to know  . .  I wondered how much fuel is returned on the 2 line mechanical pumps.   

My overall plan is to install Sniper fuel injection . . .  the first step is a electric fuel pump.   I am intrigued by a kit that Aeromotive offers, with an in-tank fuel pump that sets inside a cylindrical foam enclosure.   The return line pumps the fuel back into this enclosure.   They claim it will work in a 6" deep tank.   I am sure it will work fine with a reasonable amount of fuel in tank,  but curious what will happen when tank gets low.

I am thinking about doing this in 2 steps.   First to see how the fuel pump works in real life conditions.  I will be installing an adjustable pressure regulator at the carb, that will reduce pressure 1-7 psi.    If this seems to work in various offroad conditions,  then I will install the Sniper.   That will take more work to get sensors etc installed . .   and will be the second step.
