Upgrading in tank Fuel pump

Upgrading to Sniper with considerations for in tank fuel pump and upgraded relay
Year of Truck
1989
Truck Brand
Dodge
Model of Truck
D100

General Information

Going Sniper ignition and carb setup. My question is around the in tank fuel pump. I have pulled the tank and pulled the fuel module. I have replaced the pump with a Walbro GSS340 pump with sock. I pulled the hose attaching pump to model and replaced with high pressure hose. My question is around the connector to the module and do I just clip off the old relay wires and replace with the new relay and wiring harness? I know I need to keep the sender and gauge wires, however, there is one white wire that comes from the loom to the module and it splits into two white wires.

In my A100 I have a custom-built tank, and I am now using the Holley in-tank pump unit with a separate sender unit capable of the 10-70 ohms as per factory spec - to align with gauges. I looked at the Walbro unit you talk about and see it delivers at around 80 psi - slightly more than the Sniper system needs which is 58 psi.
Have you considered adapting the Holley pump to fit the tank opening in your truck?
