Fuel Tank Sender Update

Fuel Sender Gasket

When re-fitting the fuel sender, we utilised a custom TPU gasket. By adjusting the infill density and wall thickness during the printing process, we were able to fine-tune the gasket's compressibility and seal quality 

*Update* - The TPU gasket looks to be a little on the firm side and petrol is leaking from the sender. Sourced the correct rubber and cork alternative to replace.

Fuel Sender Float

For the floats we tried a couple of different wall thicknesses and left them to soak in petrol for a week or so to see if they held up. The good news was they all floated but not as buoyant as the cork. These were fitted with the TPU sender gasket, although the gauge functions I suspect our initial thoughts on them not being as buoyant is the problem.

 

With the goal of re-fitting the tank the next day, I turned to Amazon for large pieces of cork. I ended up using two 50mm keyring floats, and cutting one in half did the trick perfectly. After doing some research, I found several recommendations to seal the cork to prevent it from drying out over time.

Re-fitting

Balls are too big for the hole..... 10 seconds on the belt sander, re-seal and we are finally good to go.
