Stock gas tank size needed for in tank fuel pump order

[Analog]

I need to order an in tank fuel pump for a 71 Wagoneer for a sniper EFI system. I plan to use the Holley die cast retrofit pump. Holley suggested 12-129 which I think is incorrect because the Holley sniper requires 3/8ths supply lines and that model is 1/4. It looks like the 19-350 is the correct pump. My main question is about the depth of the stock tank. I can't get a measurement today so I thought I'd ask here. The Holley pump will work in tanks from 6" to 12" deep. Can anyone confirm that the tank is within that range?


Thanks,

last time I measured about 11 1/2" to be slightly above the bottom of the metal tank on the 74 for the fuel pick up line from the top of the metal ring for the fuel intake
