The kit come with full instructions in regards to wiring pumps. If you bought the lc3 controller it’s pretty straight forward, if not your going to have to wire up some relays. The vacuum line will need to be drilled on the top hat of the supercharger. The gas level sender is not polarity sensitive as indicated in the instructions and kit provides the necessary butt crimps for the install.

Help with Fore innovations pump Install
Hello guys! I have another post but I had no luck with your answers so hopefully here is different!
So im about to start a build, and I have a L4 Fore Innovation triple pump that I will be installing along with the build.
I need help with wiring, how to wire each pump and also the gas level sender. Also I need help with where to tap or get a vacuum line for the sensor and press regulator.
Thank You guys!

Thank you for the help! So vacuum line out of the top hat of the blower! Great and gas lever sender no matter which cable goes where. But now, I did buy the LC3 but it does not come with wiring instruction. I know basically the power that goes to the stock pump will now feed the the main pump, but the secondary pumps i heard they are boost activated so they have to be wired to the pressure switch? Do you have or know someone or somewhere to find the wiring instructions?The kit come with full instructions in regards to wiring pumps.

Yes I have it. I’ll download it tomorrow when I get home.Thank you for the help! So vacuum line out of the top hat of the blower! Great and gas lever sender no matter which cable goes where.

You will have (2) blue wires on top of the fuel hat that will connect to the same wires used from the factory harness. These are the only wires you will use from oem harness. In the tank you will have (3) quick connect plugs that will connect to pumps ( doesn’t matter which one you use) and the (2) blue wires for the sender that you will splice into the factory sender.
Basically you will run the #4 positive wire from battery to anl fuse to lc3 input side and #4 ground from chassis/battery etc to lc3.
Drill and tap supercharger hat for hobb switch and run lines to trunk
Install wiring for pumps 1-3
You will tap oem fuel pump signal and wire into lc3 along with hobb switch wiring. ( I’ll send you instructions for this later)
All lc3 wiring should be pre-soldered so that the wiring doesn’t work itself loose. I found it hard to do this to the main power cables due to the size. Or you can get what’s called electrical pins but I didn’t see the need for that.
Thank You bro! This helps alot. So ill wait for your instructions to start the pumps swap. Ill be honest the wiring is driving me nuts!Yes I have it. I’ll download it tomorrow when I get home.

Also I was thinking drilling the hole for the vacuum line on the back driver side. See picture for an idea! So the line is short and only run for a couple of inches to connect to the boost/vacuum manifold.

That’s probably the best placement to keep line short as possible. I didn’t want it to be visible.Thank You bro! This helps alot. So ill wait for your instructions to start the pumps swap. Ill be honest the wiring is driving me nuts!

Mine wont be visible either. I wont open hood for them to seeThat’s probably the best placement to keep line short as possible. I didn’t want it to be visible.
Wow man, is pretty straight forward. I was stressing over something that is quiet simple.Here you go
Thank You for the help!! Appreciate your time!
Im getting ready to install this system and if you could help me with a couple things
did you have to drop tank to get lines to hat
where did you get the factory fuel pump control wire from, this is the one it says to hook up with number 1 pump.
Barth rells me to hook up two pumps to run with the factory wire
i ordered the inline fuel pressure switch to place on the outlet of the rail
i alreadt have a bap so intake is drilled, ill just place hobbs switch there
thank you for your help

no need to drop the tank . why pressure switch ? FPR all you need and hob switch , don't run both pumps constantly , you heat up the fuel pretty bad .

Correct on not needing to drop tank. Can place a spacer between tank and body so you won’t have to cut floor pan for fuel fitting clearance.no need to drop the tank . why pressure switch ? FPR all you need and hob switch , don't run both pumps constantly , you heat up the fuel pretty bad .
Yea there is no need to drop tank. A spacer like El gato suggested would work just fine. Or for less added parts, cut a little piece of the floor pan to have clearance to run lines.
And to run 2 pumps at a time while not on boost or low boost might not be a good idea, you will heat up the gas to much. Thats why you have the pressure switch to activate secondary pumps at a certain boost level. Im not sure why Barth recommended that, I dont know your set up. But if he recommended that and he will be your tuner I would follow his instructions!

Seems like that was pretty straight forward for an install
