Holley Sniper EFI Returnless Self-Tuning Fuel Injection Systems 550-511D

[TGrandWagon]

Has anyone installed one of these with the in tank pump?
If so, was it hard to install the fuel pump? Any issues or concerns.
Getting ready to buy one and was going to also buy HolleySniper EFI HyperSpark Distributor Kit to work with it.
