Well, here we are again....Mark 4. Ostensibly the same as Mk3 but with a polysulfone sensor tip, to see if we can overcome the issue of it resisting petrol, which is a bit important for a fuel sensor?
This time I also stopped trying to mess around utilising the existing wiring through the sensor and drilled right through the epoxy potting in the base and rewired it from scratch, re-epoxying it afterwards. The insides are completely sealed from the fuel, so that only the tip gets immersed in petrol
This has been working fully wired up to the bike but not as yet immersed in fuel inside the tank.
Next I need again to subject it to a few days soaking in fuel to see whether we now have a viable alternative to the OEM one.
The new sensor is about £24 delivered, so I think parts costs are now about £40.
