I will but haven't yet. I plan on teeing into the front and rear tank rollover valves into the auxiliary port on the Rick's hat. There is a port that will allow the factory fuel tank pressure sensor to work as well.

The tank has to vent to atmosphere somewhere, stock is through the evap system or charcoal canister. Connecting the front and rear of the tank to the middle of the tank will not do anything.

Agree, the aux port will tee the front and rear vents together and go to the charcoal canister.

Might be a little too late since i already purchased a couple of painless performance universal relay kits.

Would be nice to get like a break down of this one, to kind of mimic it. The issue with my NNBS is trying to pin into the FPCM, to avoid buying and paying the extra charges to tune it out.

Edit: Actually i came across this thread before, and did call racetronix, and sent me to someone who was like a vendor, since supposedly racetronix doesnt have an actual "tech support".

Quite interested. Anyone know how the fuel level sender wiring is connected? Any word on the ID of the in-bucket hoses and Y?
