Re: Bubbly Fuel
Run as much of the fuel line in steel as you can.
Make sure you have the return hooked up correctly.
If you are seeing bubbles before the pump, you are drawing air into the line somewhere...
Tank pick up not having a seam soldered,
rubber hose allowing air to leak in,
Pinhole in the line somewhere,
If the bubbles were after the fuel pump, I'd suspect the pump diaphragm also.
It would take a pretty good amount of bubbles to starve your engine for fuel.
Take the fuel line off at the carb.
Attach a FUEL LINE (Not Vacuum Line) to the steel fuel line you disconnected from the carb.
Take the coil connector off the ignition coil so the engine can't start, and you don't get stray sparks.
Stick the fuel line to the bottom of a large glass jar, or clear gasoline safe container.
Ten seconds of cranking the engine should net you well over a pint of fuel in the container.
If you don't get good pumping action, and good pulsing fuel flow...
The tank or fuel lines are restricted, or the fuel pump is bad.
If you do get good volume and flow,
crank the engine again with the fuel line all the way to the bottom of the jar,
do you see bubbles coming out with the fuel?
If you don't get bubbles here, you probably don't have an air leak big enough to worry about.
(Always worry about Fuel leaks!)
If you do get bubbles, start looking for that air leak we talked about...
Let us know what you find!!
