Looking for some help here again..
I posted about this Ford 3400 tractor before. It was about the fuel pump.
So here is what I did:
Clean out fuel tank, put in new fuel petcock, cleaned out carb, installed new fuel pump and new in-line fuel filter
So I ran it for about 1 1/2 hrs or so no issues, all of a sudden tractor stops running. Look at in-line fuel filter no gas. Pulled a plug had spark but no gas on plug (bone dry) the fule filter was about 3/4 full when it was running good.
I cracked it getting no gas. Towed it back to the shop let it sit. That was Fri let it sit til Sun morning, fired right up first crack. In-line filter 3/4 full.
Seems when after running awhile, gas stopped flowing to carb.
Any help please.
Thank you
Rocky
 
What else could it be right?? Just crazy, sat for a day and fired right up.
When it stopped running I was so mad, wasn't thinking to crack the cap.
Thank you I will try to crack the cap or just go buy a new one.
Great thank you.
 
You either still have floatables in the tank that is plugging the screen or the tank is not venting. Run it until it acts up again, then, after it quits, open the fuel cap and listen for an inrush of air (vacuum). If you hear that... replace the fuel cap. If nothing, then you need to have another go at the strainer in the bottom. It's not uncommon for them to plug quite often until you really get the tank empty and clean it out good.

Look for a "floater" inside the tank that will cover the outlet. Once had a Super A with a similar problem. Inside the tank was the cap from a plastic milk jug that would occasionally drift over the fuel line and the vacuum of the gravity feed was enough to hold it until it emptied the carburetor.
 
It's a new fuel pump just installed a few days ago.
It runs fine and all of a sudden no gas coming thru in-line fuel filter.
Not sure how I would ckeck the fuel pump in this situation.
Walk me thru it and I will sure try.
