There are lots of Sniper conversion threads out there, I'm posting my version with the hopes that someone will find this information helpful for their application.
Thanks to everyone who has posted their Sniper conversions, I looked at many threads to piece together my plan for this truck.
I am starting with a 9/72 FJ50, F155 engine. I bought this truck in 2014 with a Weber 38 DGAS and all evaporative/emissions components removed by the PO.
The PO also made some other questionable non-stock mods to my rig so this wont be a concours quality OEM conversion.
The truck runs very well but the hot starts and throttle modulation with the Weber leaves much to be desired.
I am using a Sniper 2300, Redline brackets/adapters, 6AN fuel system, and an in-tank Walbro pump (Tanks Inc PA-5) with a Tanks Inc. Weld in Fuel Pump Recess.
This fuel system will allow me to avoid raising my seats and should manage sloshing/fuel starvation with the in tank reservoir tray.
A couple parts are still on the way but I have most of what I need so lets get started.
Step 1 - Install Sniper Water Temp Sensor and Fill/Burp cooling system.
I used the head port behind the carb (w/redline adapter fitting), there was some sort of evap sensor installed here but this was unhooked by the PO so not sure of it's exact function.
(I wanted to do this with the Carb still operational so I don't have to worry about air pockets when firing the Sniper)
Step 2 - Remove Carb (incl adapters) and Fuel System
(I dont have a photo but I used a redine fuel pump blockoff plate where the carb fuel pump was located)
Step 3 - Install 02 Sensor
Note that I have a 6-1 header and I welded in a sensor bung last winter knowing that a Sniper conversion was imminent.
I installed the bung tilted towards the engine per Holley's recommendations and I had plenty of room to install.
Step 4 - Install Sniper Manifold Adapter and Sniper Unit
(The redline bracket/hardware is very high quality and fit everything perfectly)
(Note Sniper water temp sensor location)
