I remembered your install. Thanks for the link as a reminder & for sharing the documentation of the install for us. I made notes & even came up w/additional improvement ideas (stainless parts & additional baffling).
My concern after researching, is these retro-fit set-ups still seem to keep the pump running constant thus heating the fuel (from the heat generated by the pump constantly running @ full speed). Obviously, being submerged is going to help a lot vs an external pump. I'm still trying to figure out what (if anything) the engineers did to help compensate in newer set-ups (think pre-GEN IV LS).
I know the GEN V LS set-ups started using PWM control of the pump. This modulates/runs the pump only as hard as it needs to maintain the required pressure vs. a set/full speed. This apparently really helps extend fuel pump life while minimizing heat soak from the pump. But, the GEN V fuel modules are not cheap & require ECU control help.
I just don't want to spend $5-600 on a set-up only to have to worry about pump related issues (I like to drive my stuff a lot) & then spend more after. I know the set-up like yours CAN/does work especially when under limited conditions (staying local). But, I might want to drive out to a GitDown someday, or the 2020 Power Tour, or a bucket list trip (Bonneville), or to visit my parents in Georgia. I don't want to be stuck roadside because of a dead electric fuel pump....
