Hello Everyone, after much reading on the internet about the MFSSB from winwing, and since people were not all satisfied with the mfssb, it was only after this thread I decided to buy it because I thought : Hey, I will figure out something.
After much trial and error, I found one easy solution. I measured with a filler gauge the gap between the bearing and the pressure sensor and after that found that the fuel injection hose clamp were really near that thickness I needed. Too thick in his original form, I sanded it until it fitted tight. It wont compress since made of stainlessSteel, cost about 3$ top. Been using this for a full month and its awesome.
The settings are now in force only and feel Ultra precise.
In the picture you see the Clamp on the Sand paper, and on the other the clamp fitted between the bearing and the pressure sensors.
For reference The fuel clamp I used was Tridon FI8 Fuel hose clamp and the sandpaper was 3M #02433 coarse emeral paper. Im but other type of similar clamp and sandpaper would fit too.
