G’day Warren. I’ve had a few dramas with the float tank on our D85a. I actually had fuel pouring out of the breather for the float tank, just below the floor panel. I ended up disassembling the tank, cleaning the float valve and tank completely and reassembling. Well it fixed it for a while. Turns out debris in the fuel tank was holding the float open. I repeated the cleaning process and then installed a pre filter with water trap at the back of the main tank. Never had a problem since.

@@richardlincoln8438 Well i guess that depends on how far you go back. In the days of distributor points you had a damn good chance of getting your vehicle going again on the side of the road. Today you are out of luck. Modules for multiple functions on these autos that are unobtainable. Try that in the middle of nowhere and no help for miles around. Not many even want to stop and help anymore for safety reasons and i don't blame them. Cell phone coverage isn't everywhere either. Horses were pretty reliable. LOL

G'day again Warren, I did comment in the last vidio about the little "side" tank. The float valve is basically a carby float and needle seat. You should be able to remove it through a round hole/plate on the top of the tank with 6 small studs. Theres a gauze mesh filter at the bottom. I can't remember if it's for the supply inlet or outlet to injector pump. Like I said in the last vidio comments it's been over 40 years. I also belive this was a Cummins part as it was fitted with these 743 type diesels in other applications. cheers, Butch.

The Cummins PT fuel system requires a float tank in certain applications where the fuel tank is providing a head of fuel. I have never seen them on application where the fuel tank is only just above the crank centre line as engines would often have check valves installed. Typically on marine engines with check valves fitted you do not need a float tank unless you are more than about 1.5 meters above crank centre line as the head of fuel on the return line puts the return restriction above its maximum limit. I am guessing this engine does not have check valves and therefore anything over the height of the injectors could flood the engine with fuel as atleast one injector is open at all times. The return fuel if not protected by check valves can also let fuel back into the engine if the return level is higher than the injectors. Cummins had 2 different size float tanks that where / are available. The one on this machine does not look like a Cummins part. The float tanks often have a breather on top as well. My advice is to run this breather higher than the supply tank incase you have a faulty float. i have seen them crack, fill with fuel and sink, letting fuel flow through and out the breather, I have seen a trawler put about 5000 litres into a bilge - not nice. If you have a PT engine take a while to shut down you may have a restricted return line.

I've got an old JS6 with t he same pump and flange injectors and it coasts to a stop (basically burning what fuel is left in the injector after the pump is put in no fuel) and has a little fuel knock when it starts. I'd say that 220 is fine, time for the dozer to go push fire roads in.

Railroad had brush cutters that had all the glass covered in mesh. One of them fired a rock through a car window going by hundreds of feet away, hitting a girl in the head. Never heard any more about it just that it was word of mouth on the shop floor one day and that it had happened in another Province (Canada). This was back in the 80's/90's. It had hydraulic motors that drove flywheels with cutters at high speed. Forget the RPM.

I wonder if it’s been parked up for a while. With what the customer is describing, if the valve stem seals are on the way out, oil will leak down into the intake/exhaust and they smoke like crazy for a while till oil the oil is burnt off. And with the exhaust leaks the smoke will make it look like the engine is on fire.
