Re: HERE'S A CHEAP DIY RESERVE VALVE!
It would be so easy for someone to make a replacment fuel shut off with a reserve on it like a motorcycle has. I bet someone here on this forum has manufactoring skills.
I got me a bright idea for a reserve valve!
Start with any new fuel tank, or THOROUGHLY clean out your existing tank.
Pour in the amount of WATER(Not gas!) you want as your reserve, be it 16 ounces or whatever. Look into the tank with a flashlight and mark the tank's outside where the liquid levels out.
Empty the water and drill the tank on the level and convenient to run a 90-degree fitting.
Braze the fitting into the hole with the nipple facing where you want it to.
Thoroughly clean tank and check for leak at the fitting.
Run the fuel line from this fitting to the carb.
Now cut the fuel line and install a tee-fitting.
Run the third fuel line from tee-fitting to the tank's petcock. Keep petcock closed.
Fill tank with fuel, start engine and enjoy the drive.
When engine runs outa fuel or starts sputtering, reach down and turn the petcock lever.
VOILA! Reserve fuel!
You'll have to figure out for yourself how much of a reserve you need.
Experiment close to home.
Happy motoring!
