In my previous post I detailed about all the electrical work I did on my tractor, after over a year the only problem turns out to be a bad gauge.
Tonight I replaced the gauge, when I did the rewire I also replaced the fuel tank sender (to match the new gauge) it was reading 1/8 to 7/8 instead of E to F, while I had the dash apart for the bad gauge I removed the sender and shortened the arm on the float by about 1 1/2", I figure that should be close.
Before putting everything back together I decided to drain the fuel tank completely to see how close the empty reading is (Empty is really the only reading that I care about).
I disconnected the fuel line before the fuel pump and drained it into a spare gas can.
I discovered that there is a petcock on the bottom of my fuel tank (It's tucked in behind so much cowling and linkages that I never knew it was there) it seems to be off-on-off, and the on position is literally dribbling the fuel.
It's a 1/4" fuel line it is not even flowing a steady stream.
The tractor seems to be running at full power so I believe it is getting enough fuel, but the pitiful fuel flow bothers me, when it finally drains do any of you think that I should remove the petcock and either try to improve the flow, or just eliminate it completely and add a fuel shut-off inline (or not bother at all)?

Does removing the cap make any difference?

Often there is a fine screen on the fuel tank outlet and it may be getting blocked. Removing the valve assembly when the tank is empty should let you see what is happening.
