I seldom drive the rx8, but the excessive Mazda recall notices in the mail wore me down and I brought it in. Airbag recall was performed, and the 1017E recall for fuel leaks.
While it never leaked fuel before, the work performed by the dealership ensured that it started to. After filling the tank, the garage smelled of gasoline. Passenger side fuel tank was slowly leaking underneath the car, so I pulled the seat and found a puddle.
Page 16 of the 1017E recall procedure describes a fuel leak inspection through 5-6 hard braking events, but what can really be expected when the dealership failed to even clean the area per procedure. I ordered a new gasket as it was logically the culprit, and several fuel pump tools.
The 1st to arrive was no good. Thumbscrews and shallow grips were useless.
The 2nd tool by OEM Tools was adequate for breaking loose the fuel ring using a mallet, and involved multiple tightening/loosening of bolts and re-positioning.
The gasket as installed by the dealership was pinched and not sealing properly. As a temporary repair, I flipped the gasket upside down, and re-tightened enough to avoid leaks. However, the OEM Tools 25156 could not be trusted for final torque without damaging the plastic ribbing, so I ordered a third tool.
The 3rd tool from Fattimotorworks was used to apply final torque. I took the spec torque into consideration, but stopped short based on mechanical feel and the visible twisting of the gas tank.
To use the FMW tool, find the correct orientation until it slides past the gas tank and drops into place. Once in place, it is not going to slip and damage anything unless someone over-torques or mis-aligns threads to begin with.
Possibly the best rx8 fuel ring tool available on the market due to gripping every single rib. No idea how good the Mazda tool is, as I could not find the Mazda SST Fuel Pump Ring Wrench available for purchase.

Reason: proof reading
Is the FMW tool available? They quit making them at one point and I wasn’t aware they started reselling them. I found out when trying to buy one a year or two ago. IMO it is superior, that’s why I wanted one.
A 2-leg tool is too easy to lean over when you’re trying to torque it the extreme end of the torque range and is also more susceptible to damaging the ribs as mentioned. It needs to have at least 3-legs for stability but even the OE Mazda tool has 4-legs. A full diameter plate or ring is the best design and is how a lot of other specific make/model fuel ring tools are made.
I thought about having some made after FMW quit selling theirs, but never got around to it. It’s pretty easy to get that laser cut once you have the pattern from the ring.
that’s the same webpage from 2+ years ago when the told me it was discontinued, they never took it down and I had to chase after them getting an answer because they don’t respond
they were having them made through some guy and he left the company, then the company wanted to jack up their price.
Randomly found this page haha but ya we did have a gap when the tool was not available, they are back in stock now. We have a steady company near us making them now.
I’ll go on record to state that I ended up buying the Fatti one and it’s way better imo
the two leg type are particularly bothersome, even the BHR one (which I ditched for the Fatti). They all really need 3 or more legs (Mazda factory version is 4 legs) to remove the tendency for the tool to slip off or fall over easy. The Fatti tool eliminates that situation entirely.
