The fuel line where it runs under the cab is rubber tubing and a mechanic suggested any low spot will act like a water trap and its in that line that froze up yesterday. I know this because between the fuel shut off at the tank and lift pump I had no flow. It wouldnt let go with a blow gun on the air compressor hose when i tried either.I put about a quart of freeze protecting fuel conditioner in this fall when I replaced the fuel filters. Yesterday I also added another quart of methyl hydrate and 1/4 of a quart of 2 cycle engine mixing oil. After it warmed up it did let go; I blew air into the tank for several 10 second intervals through the line that was froze from the lift pump end hoping it might help blow the water back into the tank so itd mix with the methyl hydrate. After I got a flow going again I reattached the fuel line to the lift pump, bled it out and got it running. My questions are would the air nozzle actually blow the water back into the tank and do I have enough methyl hydrate and conditioner already to keep it from gelling up again this winter? Tks

If by fuel you mean diesel. Save your self the grief and use #1 diesel.

Keep the fuel tank full. Condensation will form in the tank while setting, the lower the fuel level the more condensation. Some will say it is just snake oil, but I would liberally dose with Howes, Power Service, or Stanadyne fuel conditioner at each fueling.
I expect you are running this unit a lot less than you used to and that does make a difference. The fuel doesn't really get warmed up as it used to. Working equipment until gearboxes and reservoirs are warm/hot to the touch helps evaporate moisture out.

It could be that every time that you add treatment to disperse water that you are using 60% of what you really need to eliminate all of the water being produced each year by condensation. Every year the amount of water increases until finally it is up to where your suction line pulls it. I think that you need to drain off the bottom until it runs clear, eliminating all water and crud.
Philip, you intermix the terms gelling and freezing. Two different issues at play. Gelling is when the wax drops out of the fuel, usually between 20-10 F for regular summer or number 2 diesel. The fuel will still flow but the wax blinds the filter starving the engine. Fuel conditioner is the remedy, but needs to be added when the fuel is above the gel point.
Freezing is water in the fuel, which sounds like what you are dealing with. The methyl hydrate will help, but the water/methyl hydrate mix will collect in the filter or water separator if the is one.
I have a Massey with a plastic tank that I usually dump a pint of water out of the water separator each year. And I dont even use a tank of fuel per year.

You will have to ask them or request the different fuel than what is normally on the truck. IF the people you get your fuel from are reputable they should have the fuel already blended for the climate you are in. We don't use anything in the winter other than what they bring in the truck with no problems during the winter. Several tractors don't get more than a few hours during the winter either. Sometimes all at once. We have drains on our tanks at the bottom to let out water condensing in them during the year so the equipment is pretty much water clear. That will help along with keeping your tank full.
As for the froze line that is water not gelling. Keeping water drained out is the best way to solve your problems as well as the keeping tank full.

It looks like you could simply take 4-5 feet of fuel line, loosen that clamp, pull your blocked line off and stick your extra piece on the barb then just let it drain into buckets. Once it is empty you can remove the tap assembly and let the rest out, then pour some in the fill to rinse it.
Thank you, that may be the only way to get it drained and
clean as there doesnt appear to be a drain plug on the
bottom of the tank on either side. There is a return line right in
front of the line coming off of the tap, not unless that is a drain
also? That return is directly at the top of the first fuel filter.
