Without a surge tank that will result in the HP pump starving and a pressure drop out just like using the OEM pump as a primary...so not a lot of help
There needs to be enough reserve in whatever encloses the primary pump to prevent the pump from running out of fuel
I think I have tried about 8 different setups....that's why I can tell you what didn't work...I think I tried almost everything humanly possiblebefore I said F it and did the surge tank setup
And if anyone thinks there setup works..post it up..but remember I'm talking about a track setup that is pulling over 1.5G's when it causes issues...not slow assed track day stuff

bonus of using a fuel filter - need not be certified. A pure surge tank needs to meet the same ratings that a fuel cell does.

You will lose the fuel level sensor, need some plumbing and electrical work but will work. Not perfect solution but will work. Best solution is a stock pump feeding a surge tank. I might try 034motorsport surge tank with a 044 inside the tank. Radium is nice too but expensive

I planned to install other OEM driver side canister with OEM pump in the passenger side. I see the level sensor connector and fit to OEM connector in the canister. the only unknown is when use OEM pump in passenger side goes empty .for that problem I get relocate the return fuel from engine to feed passenger side

I just put in a switch so I can shut it off when I am not on track
I also left the OEM suction assembly hooked up and attached the pickup to the pump body...
Be careful how you plumb the returns so the fuel stays in the cups as much as possible...thats where you will have problems.
Are you running return style system?

the return go direct to canister feeding fuel . i think if the rx8 pump feed much fuel faster to the driver side of the tank i regulate the pump with a reaistance en positive cable or instal a low press fuel pump.

OK you said the passenger tank goes empty with the OEM pump in the passenger tank with feeding the return fuel inside the passenger tank?

No
I said that the fuel cups tend to empty faster than they are refilled when there is a high cap pump and a return style system. That you need to be very careful how you set up the returns so you don't make it worse than the stock returnless system
And that it didn't work for me on the track
