Fuel pump boiling fuel!

Recommended Posts

I was mowing with my C165 today and it sputtered and stalled like it ran out of fuel. When I looked at the fuel line coming from the fuel pump to the carb, the fuel was boiling!! Do I need to change the exhaust route or ?

I had a 520 do that and the fuel line was resting against the oil filter getting hot.

 

Just re-routed it a bit and all was well.

 

Just re watched your video and it looks like you may just be sucking in air somewhere.

 

Double check all connections and check the fuel line for a crack.

I thought maybe it was just air. I need to get an infrared thermometer. The air cleaner was scalding hot when I brushed against it though

I agree with Cleat, that looks like air.    What are you using for fuel lines?

I'm using the clear pvc type line. I just thought it was weird that it ran fine again after it cooled off

Maybe your cooling fins are getting cloged with grass, blow the shroud and fins on the head with some air

could be the pump is sucking air. Fuel pump might be going out.

      Waiting on the eBay electric fuel pump to show up for the C165. Only thing I'm not sure about is what to do with the old mechanical one. Do I just leave it in place or do I need to make a cover plate with the a gasket and remove it?

      So I rebuilt carb and replaced fuel pump, thought fuel pump would fix my problems. No such luck! Still stalled out when she got hot. Took apart fuel tank shutoff, cleaned and lubed o ring, knocked some dirt out of vent tube with long wire, blew long fuel line, drained tank and tried some air pressure both ways, tank fuel outlet, and thru vent tube. Doesnt allow hardly any air flow either way? What is between tank and vent tube? A really small orifice, or some sort of pressure valve vent device? Put it back together and ran her with coffee filter banded over cap, NO PROBLEMS! Was so glad to move some dirt that I never tried putting cap back on! I think maybe there was blockage at tank shutoff, valve was very stiff and difficult to turn. Looks like a major ordeal to access fuel tank???
      I will try putting fuel cap on tomorrow, but I had ran her prieviously with cap loose so I think my problem is solved. Vent sure doesnt seem right though?

      Hi there,
       
      We recently became the proud owners of a 1976'ish C-120. When we purchased the tractor it wouldn't start but the previous owner believed this was due to a faulty solenoid.
      Anyhow, I finally had time today to see if it would run. On initial inspection, there was a definite 'click' on attempting to start. And after a few attempts, the starter turned the engine over and it fired - so I think we actually have a 'sticky' starter, rather than a dodgy solenoid? Anyhow, I then took the tractor for a 'spin', and not knowing how long the fuel I had put in might last, after about 30 minutes the engine spluttered to a halt. Oh dear out of fuel
      I filled the tank with what fuel I had left in my can, but on attempting to restart, the engine turns over but refuses to fire.
       
      Having run out of fuel, is there some sort of 'priming' process that I need to go through before I will be able to get the engine to fire again?
       
      Any advice gratefully received.
      A newbie

      My week long effort to get my Raider 10 to fire finally is resolved....quick back story that might help anyone else. I was totally baffled that I had spark and 90 PSI compression and even using starting fluid got little more than a sputter. The problem was I just needed to add triple the amount of starting fluid or gas and the thing fired right up which it hadn't done before. What a relief !!!
      Is it wrong to hear it run strong even for 3 seconds and get turned on?  lol.
       
      Sorry to jump posts but I figure most people reading know about 100 times more than me so.....
      Carb....LME 29. Mine seems sorta OK but is there an aftermarket replacement out there for under $100? I kinda like the idea of a brand new carburetor.
       
      Front axle on my 1970 Raider 10......I have a really nice 42" JD snow blade with the bracket that bolts to the frame in front......is there any reason I couldn't weld 2 L-brackets to the front axle member to bolt it to. My concern is since its cast.....how well can that be welded to? Or should I try to weld some brackets to the frame instead?
       
      Special thanks to Strauss, Kevin, and especially Brian for help, info, and troubleshooting.
