Any way to modify the fuel tap to provide for a clear tube sight gauge?
Something like this:

Clear fuel line is easier.

Be the first thing to break, always be in the way. I can see your knee or some such compromising its integrity.

Easier to T it off the hose under the tap, using clear tube as Mr Prince says, rather than “glass.”

T/Trashr - good idea- one on each side & the tube spans to both?

I’d expect that one on one side is enough.

What is the top of the sight tube connected to? And of course very industrial looking………. It’s always fun to think of additions to a design, but This may be a bit exaggerated in respect to “form follows function”. (something my Wife and I can have endless discussions on…. ;~] )

What KC is alluding to is unless the top of the line is vented the fuel will not go up the hose.
Why not put in a fuel gauge on the dash or handlebar?

Hi JBMorris, That would be handy.
There were some gas caps for some bikes that had stem built into cap with gas gauge. Haven’t seen one in years.

The sight glass would need top vent into tank above fuel level or to atmosphere with an inverted J tube at top. Atmosphere vent would impractical if think.

I know this. You see a few inches of fuel in tank. You’re walking soon! You run out of gas. Looks like an inch remaining. That’s normal. Dry tank is explosion hazard.

Tipping bike to get some fuel to reserve tap. Gives maybe 2 blocks at most. My reserve is 1 US quart + 1 cup. 40mpg do the math. Pray Goggle shows gas station near by. Been there done that! Accurate gas gauge would be really nice!

Yes 'have run out of gas a few times,
Not much room under the tank anyway.

Perhaps this is more sensible, if you can make a hole in the tank.
