So while figuring out that ******** I took mental breaks from that by installing the awesome CJM dual pump hanger.
I am using a Walbro 535 as the primary since it has no check valve and a 525 secondary. Both pumps have the Holley hydramat socks on them so I shouldn't run into fuel starvation issues
I realized this was overkill after but it's there to stay. 6ga wire with a 50amp circuit breaker feeding the 2 relays. Bolted them to the underside of the shelf above the fuel pump access panel.
4psi hobbs switch that I'm hoping I can adjust to 10psi for the secondary pump
