Fuel Tank Mod
 

Having bought one fo the great fule tanks HandyAndy sniffed out I'm now looking at making a mod to it. Knowing that there are a few cunning people so thought I would see what suggestions people come up with.

The current fuel sender is fitted to the centre of the tank. I want to replace this with a motorbike unit as I plan to use bike style clocks. I've got a sender from a Honda Blackbird. It is perfect, arm length, float travel etc - the only issue is I need to fit it on ones side of the tank. I can easily blank off the old sender hole. Then I need to fit the new ones - only 4 mounting holes. So I'm wondering what is the best way to fit the new one? Fit a thick threaded doubling plate? turn some threaded inserts, fit from below and tig on top? make a thin doubling plate and weld nuts on bottom then weld to top of the tank? Rivnut and fit a thick gasket?

Any crazy ideas welcome!

Off the shelf senders are just self tappers with a thick gasket, but flush fitting riv-nuts would be ideal with a rubber gasket and sealed with a specialist sealant; Dirko non-setting silicone:

Not the cheapest but excellent sealer.

Out of interest how thick are mdoern tanks? These tanks must only be about 0.5mm thick by eyeball. I don't think you could use flush fitting rivnuts in something this thin but I must admit i've never used them before.

Make the mounting plate for the inside of the tank in the form of the bike gasket,drill and tap the plate for the mounting screws again to pattern of gasket and you have only five holes in a flat sheet of metal to contend with to seal,I would use PU/Sikaflex to seal plate inside or cut groove for o ring seal.

Thanks for the ideas guys - will have a ponder and see what option I chose. I like the idea of not having to weld anything to the tank. Will let you know how I get on.
