I've seen some cheap fuel pumps on Ebay and have a redundant switch on the handlebars left over from heated grips. Still, I'd like to keep it practical and simple hence, one of those 'bleed bulbs' and take it from there. I'll let you know how I get on.

Adding to an old thread...

Aux tanks for FI (fuel injected) Wave and Innova's


This week I fitted a camel aux tank to CRF250L a fuel injected Honda. It works by the fuel pump creating a vacuum in the main tank and sucking fuel from the extra tank into the main tank.

THIS SYSTEM WOULD WORK ON A FI HONDA WAVE/INNOVA....

You would need to make an airtight cap for the main tank with a feed pipe in it - the aux (extra) tank would need a breather on the top.

The plus of this type of system is - the extra tank would empty first - before the main tank under the seat - so if touring - unless you had used both tanks of fuel - you would only need to be topping up the extra tank. Plus the fuel gauge would work - the logic - once the extra tank was used up - the main tank fuel gauge would read what you you had left with correct readings.

I am so convinced it will work - I am now hunting on Ebay for a black plastic Honda XR80 fuel tank with a petcock on the bottom - for my Honda Wave 110i. Make a three point frame in the "step thru space".

I reckon the hardest part will be making a fuel cap on a lathe for the main tank. It will need to seal - have a hole - fitting in it for the vac feed pipe - and will need to come off and on easily to refuel the standard tank.

I might buy a secondhand tank for the wave ex ebay and then drill and fit a vac feed pipe in it and then seal the breather in the original fuel cap.
